Answer:

401.92

Step-by-step explanation:

The formula used the calculate the volume of a cylinder is

πr^2h

π= 3.14

H= 8

r= 4

Volume= 3.14 × 4^2 × 8

= 3.14 × 16×8

= 401.92

Hence the volume is 401.92

Answer:

[tex]3\frac{1}{4}[/tex] inches

Step-by-step explanation:

Height of the tallest conifer = [tex]9\frac{1}{2}[/tex] inches

Height of the shortest conifer = 6 + measure of one segment on the number line

Measure of one segment on the number line = [tex]\frac{6\frac{1}{2}-6}{2}[/tex]

                                                                           = [tex]\frac{\frac{1}{2}}{2}[/tex]

                                                                           = [tex]\frac{1}{4}[/tex]

Therefore, height of the shortest conifer = 6 + [tex]\frac{1}{4}[/tex]

                                                                    = [tex]6\frac{1}{4}[/tex]

Difference in tallest and shortest conifer = [tex]9\frac{1}{2}- 6\frac{1}{4}[/tex]

                                                                    = (9 - 6) + [tex](\frac{1}{2}- \frac{1}{4})[/tex]

                                                                    = 3 + [tex]\frac{1}{4}[/tex]

                                                                    = [tex]3\frac{1}{4}[/tex] inches

Radius is 4.2

Diameter is 8.4

Step-by-step explanation:

diameterd=2r

d=2×4.2

d=8.4

Plz mark as brainllest

Answer:

The answer for radius is 4.2 cm. The answer for diameter is 8.4 cm.

Step-by-step explanation:

If the line cuts halfway through the middle it is a radius, as you can see there. It says 4.2 cm, so that's your radius. If the line is straight through the circle and not cut in half then it is a diameter. The radius is half of the diameter. So if you add 4.2 or multiply 4.2x2 then you get 8.4 which is your diameter.

Answer:

2

Step-by-step explanation:

option c is the correct answer

The required value of the given logarithmic expression log₂ 16 – log₂ 4 is 2. The correct answer would be an option (C).

There are four basic properties of logarithms:

logₐ(xy) = logₐx + logₐy.

logₐ(x/y) = logₐx - logₐy.

logₐ(xⁿ) = n logₐx.

logₐx = logₓa / logₓb.

According to the problem, we will use some of the basic logarithmic properties,

The logarithmic expression is given in the question, as follows:

log₂ 16 – log₂ 4

We have to determine the value of the given logarithmic expression.

As per the given question, we have

⇒ log₂ 16 – log₂ 4

⇒ log₂ 2⁴ – log₂ 2²

Using property logₐ(xⁿ) = n logₐx,

⇒ 4 log₂ 2 – 2 log₂ 2

Apply the subtraction operation, and we get

⇒ 2 log₂ 2

⇒ 2 (1)

⇒ 2

Thus, the required value of the given logarithmic expression is 2.

Answer:

53.57%

Step-by-step explanation:

Answer:

53.57%

Step-by-step explanation:

Answer:

C= 2 πr =18.85 m

Step-by-step explanation:

diameter= d= 6m

Radius = diameter/2= 6/2 = 3m

The circumference can be found by two formulas. One by using diameter and the other by using radius.

C= πd = 6* 3.14= 18.85 m

or

C= 2 πr = 2*3.14*3= 18.85 m

Using both the formulas gives the same answer.

The diameter is the line dividing the circle into half passing through the center.

The radius is half of the diameter or the lines which joins the center to the circumference of the circle.

Answer:

If its a girl shes probaby getting bigger soon I think i she probably lost her taste in milk

Step-by-step explanation:

Answer:

Cute bunny :)

So I know that domestics are weaned off milk at about 6 weeks, so she could still be drinking, but she also could be weaning. HOWEVER, they should never loose wait during the weaning process. I would try to give her a formula (baby rabbits should be fed Kitten Milk Replacer (KMR) or goat milk, which you can buy at pet stores, or sometimes even a local veterinarian's office. Because rabbit milk is the most caloric of all mammals, we add in one tablespoon of 100% heavy whipping cream (no sugar) to each can of KMR.) and force feed it to her.

If you are not comfortable with that, you can try soaking rabbit pellets in the formula and mashing up, but there's a good chance she won't recognize that as food.

Maybe join some rabbit keeper forums or ask a local breeder for more help.

Answer:

(a) 33.7 cm

(b) 79.25 cm²

Step-by-step explanation:

(a)

Find the perimeter of the semicircle (circumference ÷ 2).

10 cm is the diameter of the semicircle.

The perimeter of the semicircle

= (10 × 3.14) ÷ 2

= 31.4 ÷ 2

= 15.7 cm

The perimeter of the shape

= 15.7 + 10 + 4 + 4

= 33.7 cm

(b)

Find the area of the circle then divide to 2

The formula of the area of a circle

= πr²

The radius of the circle

= 10 ÷ 2

= 5 cm

The area of the semicircle

= (3.14 × 5²) ÷ 2

= 78.5 ÷ 2

= 39.25 cm²

The area of the rectangle

= 4 × 10

= 40 cm²

The area of the shape

= 39.25 + 40

= 79.25 cm²

Answer:  [tex]\dfrac{33}{40}\ gm[/tex]

Step-by-step explanation:

Given

Neville place three weights in the sequence

[tex]\dfrac{1}{2}\ gm,\dfrac{1}{5}\ gm,\dfrac{1}{8}\ gm[/tex]

The total weight of the three weights is

[tex]\Rightarrow \dfrac{1}{2}+\dfrac{1}{5}+\dfrac{1}{8}=\dfrac{20+8+5}{40}\\\\\Rightarrow \dfrac{33}{40}\ gm[/tex]

Thus, herbs weigh  [tex]\frac{33}{40}\ gm[/tex]

Answer:

The length is 12

Step-by-step explanation:

rectangle = 2w + 2l

Substitute 15 with w

2l + 2(15) = 54

Multiple

2l + 30 = 54

Subtract 30 from both side

2l = 24

divide by 2

l = 12

Answer:

18- Both these triangles have the same amount of lines on it, meaning they are congruent.

Answer:

2/3

Step-by-step explanation:

When a line is parallel to another, it means that there are never going to be any solutions(they won't ever intersect each other.) To do so, the slope of the lines have to be the same. It doesn't matter what the y-intercept is.

So the slope of the second line is going to be the same as the first line: 2/3

Answer:

(2u+8)(2u+10) inches^2=4u^2+36u+80 inches^2

Step-by-step explanation:

I don't know what the options are. But I'll try to help you anyway. Is that variable for the width of the frame... u? We'll just use u.

So the area of a rectangle is found using length* width. To find the combined area of the mat and the photo, we need the combined length and the combined width.

combined length=u+8+u

(Think of it from the top to the bottom: the top strip has a length of u inches, 8 is given, and the bottom strip is also u inches long.) You can simplify it to get 2u+8 inches.

combined width=u+10+u=2u+10 inches

To find the area, you need to multiply these dimensions.

(2u+8)(2u+10) inches^2

I think this would be your answer for Part B, because it's factored.

I think for Part A, you need to multiply it all out.

=2u(2u+10) + 8(2u+10)

=4u^2+20u + 16u+80

=4u^2+36u+80 inches^2

Hope I could help you!

Answer:

y = 8  

x = 12        

Step-by-step explanation:

Corresponding sides are in proportion when the polygons are similar.

(1)      7/3.5 = 3y/x                    (2)    7/3.5 = (x + 4)/y

            2 = 3y/x                                    2 = (x + 4)/y

          2x = 3y                                       2y = x + 4

          2x - 3y = 0                                -x + 2y = 4   Multiply by 2 and add to (1)

         -2x + 4y = 8

                    y = 8                               -x + 2(8) = 4

                                                           -x + 16 = 4

                                                                 -x = -12

                                                                   x = 12

There you go.  Hope you can follow.
