Which is closest to the area of the circle?
132.7 cm2

20.41 cm2

40.82 cm2

530.66 cm2

Answers

Answer 1

Answer:

The first option, 132.7 cm²

Step-by-step explanation:

The area of a circle can be found with A = πr²

A = πr²

A = π(6.5)²

A ≈ 132.73

A ≈ 132.73 cm²

-> 132.7 cm² <-

Answer 2

Answer:

[tex]\boxed{\sf{132.7cm^2}}[/tex]

Step-by-step explanation:

You only had to solve this problem to use a circle's area.

[tex]\text{Area of a circle: }\sf{A=\pi r^2}[/tex]

Radius of this circle is 6.5 cm.

A=πr²

A=π(6.5)²

Solve.

A=π(6.5)²

A=132.73

To get the correct answer, remember to use the centimeter.

A=132.7cm²

Therefore, the correct answer is

A. 132.7cm².

The volume of this right trapezoidal prism is 464.75 ft³.

What is the height, x, of the prism?

Enter your answer as a decimal in the box.

x = ft

Answers

Answer:

the answer is 14.3

Step-by-step explanation:

The height of the trapezoidal prism is 12.3 feet.

Formula for finding the volume of trapezoidal prism

[tex]v = \frac{1}{2}(b_{1} +b_{2} )hl[/tex]

where,

v is the volume of trapezoidal prism

[tex]b_{1}[/tex] and [tex]b_{2}[/tex] are the bases

h is the height of trapezoidal prism

l is length of the trapezoidal prism

According to the given question

We have to find the value of x which is the length of trapezoidal prism.

And,

Volume, v = 464.75 cubic feet.

From the given figure

here,

[tex]b_{1} = 5ft[/tex], [tex]b_{2} = 8ft[/tex], [tex]h = xft[/tex], and [tex]l = 5.8ft[/tex]

Substitute all these values in the formula of the volume of trapezoidal prism

⇒ 464.75 = [tex]\frac{1}{2}[/tex] ×(5+8)(5.8)x

⇒929.5 = 13×5.8x

⇒[tex]\frac{929.5}{(13)(5.8)}[/tex] = [tex]x[/tex]

⇒ x = 12.3 feet

Hence, the height of the 12.3 feet.

. A right triangle is drawn inside a sphere, and the hypotenuse is 12 cm. What is the radius of the sphere? Round your final answer to the nearest hundredth.

Answers

Answer:

Step-by-step explanation:

The required measure of the radius of the sphere is given as 6 cm.

What is the triangle?

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°

Here,
A right triangle is drawn inside a sphere, and the hypotenuse is 12 cm.
As we know, for a right triangle inscribed in a circle, the hypotenuse represents the circle's diameter,
hypotenuse = diameter
12 = diameter
radius = diameter / 2
radius = 12/2
radius = 6 cm

Thus, the required measure of the radius of the sphere is given as 6 cm.

6. y = x² + (-3) is equivalent to y = x² - 3

y = x² - 3

y = 0² - 3

y = 0 - 3

y = -3

(0, -3)

y = x² - 3

y = 1² - 3

y = 1

y = -2

(1, -2)

y = x² - 3

y = 2² - 3

y = 4 - 3

y = 1

(2, 1)

y = x² - 3

y = 3² - 3

y = 9 - 3

y = 6

Decide which measurement is greater. Place the correct symbol ( <, >, =) on the line between the measurements.
5 gallons _______ 18 quarts

1 pint 4 cups _____ 32 fl oz

3 pints ______ 8 cups

13 quarts _______ 4 gallons

4 quarts _______ 9 pints

Answers

The measurements that are greater using the correct symbol <, >, =) are:

5 gallons > 18 quarts1 pint 4 cups > 32 fl oz3 pints < 8 cups13 quarts < 4 gallons4 quarts < 9 pints

How to determine the greater measurement?

Gallons and quarts

1 gallon = 4 quarts.

So, we have:

5 gallons = 20 quarts i.e. 5 * 4

Hence,

5 gallons > 18 quarts

Pints and cups to fl oz

1 cup = 0.5 pints.

So, we have:

1 pint 4 cups = 1 pint + 2 pints

1 pint 4 cups = 3 pints

1 pint = 16 fl oz.

So, we have:

1 pint 4 cups = 16 * 3 fl oz

1 pint 4 cups = 48 fl oz

Hence,

1 pint 4 cups > 32 fl oz

Pints and cup

1 cup = 0.5 pints.

So, we have:

8 cups = 4 pints

Hence,

3 pints < 8 cups

Quarts and gallon

1 gallon = 4 quarts.

So, we have:

4 gallons = 16 quarts

Hence,

13 quarts < 4 gallons

Quarts and pints

1 quart = 2 pints.

So, we have:

4 quarts = 8 pints

Hence,

4 quarts < 9 pints

A map has a scale of 1 cm : 30 km. If 2 cities are 4.7 cm apart on the map, how far apart are they in reality?

Answers

Answer:

141 Km apart.

Step-by-step explanation:

so if each 1 cm is equivalent to 30 km, we would take the 4.7 and multiply it by the 30 to get the true value.

the true value would come out to be 141 km apart.

Please mark this as brainlest.

141 miles away.

Explanation? Common sense, no?

We are given the unit rate, so we can convert it easily.

1cm = 30km, so, multiply it by 4.7 as there are 4.7cm that are present.

30km x 4.7 = 141km in real life.

64 is 4 times the difference between Sarah's age, a, and 44. Assume Sarah is older than 44.

Write an equation to determine Sarah's age (a).

Find Sarah's age.

Answers

Answer:64/4+44=a

Sarah is 60 years old

Step-by-step explanation: 64/4 =16. 44+16=60

Multiply this difference by 4, and you get 64 as the result. So:

64 = 4(a - 44)

Now you need to balance the equation. Do the same operation to both sides. To begin, divide both sides by 4.

64/4 = 4(a - 44)/4 becomes

16 = a - 44 To get variables on one side and numerals on the other, add 44 to each side.

16 + 44 = a

60 = a. Sarah is 60 years old.
