What is the diameter of a cone with height 8 m and volume 150 pi m3 ?
A. 7.5 m
B. 5V3 m
o C. 7.573 m
D. 15 m

Answers

Answer:

V = pi*r^2*h

V = 150 m^3

h = 8 m

150 = pi*r^2*8

Solve for r (the radius) then multiply by 2 to obtain the diameter.Only, this is a cone, not a cylinder.

V = 1/3 pi r^2 h

Diameter of the cone is 15 m. So, option D is correct.

What is meant by solid shape ?

Solid shapes are defined as the three-dimensional objects that are described by the three dimensions length, breadth and height.

Here,

Volume of the cone is given by,

 V = 150[tex]\pi[/tex] m³

Height of the cone, h = 8 m

We know, the equation for the volume of a cone is,

V = 1/3[tex]\pi[/tex]r²h

where r is the radius and h is the height of the cone.

So,

(1/3) [tex]\pi[/tex]r²h = 150[tex]\pi[/tex]

r²x 8 = 3 x 150 = 450

r² = 450/8

r² = 56.25

r = 7.5 m

Therefore, diameter of the cone,

d = 2r

d = 2 x 7.5

d = 15 m

Hence,

Diameter of the cone is 15 m.

What is the area of the square?
What’s the area of the circle

Answers

Answer:

Square: 144 m²

Circle: 113.04 m²

Step-by-step explanation:

The formula for area of a square: side × side.

The formula for area of a circle: r²π (radius × radius × pi)

**SQUARES HAVE EQUAL SIDES**

As shown in the photo, the side lengths of the square are 12.

side × side

12 × 12 = 144

Therefore, 144 m² is the area of the square.

-------------------------------------------------------------------------------------------------------------

The diameter of the circle is 12 as well.

But, to find the area of the circle, we need the radius.

To find the radius of a circle, divide the diameter by 2.

12 ÷ 2 = 6.

6 is the radius.

Now we plug the numbers into the equation.

**3.14 IS A SUBSTITUTE FOR PI**

r²π (radius × radius × pi)

6²π (6 × 6 × 3.14) = 113.04

Therefore, 113.04 m² is the area of the circle.

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.

A(n)=6+(n-1)(1/5)

Answers

Answer: a’(n)=1/5

Step-by-step explanation:

The first term is 6, the fourth term is 6.6, and the tenth term is 7.8 in the arithmetic sequence.

What is an arithmetic sequence?

An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.

The given rule for the arithmetic sequence is:

A(n) = 6 + (n - 1)(1/5)

To find the first term, substitute n = 1 in the formula:

A(1) = 6 + (1 - 1)(1/5)

A(1) = 6 + 0

A(1) = 6

Therefore, the first term of the arithmetic sequence is 6.

To find the fourth term, substitute n = 4 in the formula:

A(4) = 6 + (4 - 1)(1/5)

A(4) = 6 + 3/5

A(4) = 6.6

Therefore, the fourth term of the arithmetic sequence is 6.6.

To find the tenth term, substitute n = 10 in the formula:

A(10) = 6 + (10 - 1)(1/5)

A(10) = 6 + 9/5

A(10) = 7.8

Therefore, the tenth term of the arithmetic sequence is 7.8.

Answers

Did you ever get the answer?

I did mine but i don’t know if it’s correct (I haven’t submitted it yet)

Area = 1/2 * base * height

Base= b = 20

Height = BD = 9.05

Area = 1/2 * 20 * 9.05

Area = 90.5 units squared

The expression for the area of ΔABC will be A = 1/2 x CA x BD, and the area is 90.5 square units.

What is the area of the triangle?

The area of the triangle is given as

A = 1/2 x B x H

Where B is the base and H is the height of the triangle.

Then the expression for the area of ΔABC will be

A = 1/2 x CA x BD

A = 1/2 x 20 x 9.05

A = 90.5 square units

1. Jesús Colón is trying to debate weather or not to help the woman and her two young children. He thought it was a good idea because she was carrying a suitcase and a baby but at the same time he wasn't so sure because he was worried about what the woman would think and if she was racist or prejudice. He even was afraid that the woman would try talk to him in mean ways or to discriminate him just because he was both African and Puerto Rican.

2. Colón had his reputation at stake in this decision due to what the woman would do exactly. Since he didn't help the woman he regretted it and believed he should have helped her even if it would have costed him.

3. I believe he wrote this story to explain that simple actions can lead to a huge change in the future. For example if you see some one who is mean and they need help and you help them then that one mean person can become a really nice person in return just from your actions.

4. I would have helped the woman even though the circumstances because no matter my skin color, reputations, or the way i look i would help anyone because they may not know but deep down i am a good person. And you should not judge a book by its cover.
