Question

What is the Volume of a right cylinder with radius 2ft and heights 5ft? Leave answer in terms of pi please.

Answer 1

What is the formula?

Answer 2

4/3 times the cube of the radius

Answer 3

If that's the formula, then how does the height of 5 feet fit into this?

Answer 4

4/3 times the cube of the radius --> I think this is the volume of a sphere formula.

Answer 5

The volume of a cylinder equals the area of a base times the height of the cylinder

Answer 6

Okay, then.

Answer 7

The base of a right circular cylinder is a circle. That would be pi* r^2 for that and then multiply by h to get the volume. (see file attached above)

V = pi * (r)^2 (h)

@DustinMHayes Fill in for r and h and crank it out. I'll do the same and we will compare answers.

Answer 8

10pi ft to the third power

Answer 9

I need to see your steps.
I did not get 10 pi cubic feet.

V = pi * (2)^2 (5)
V = pi * 2 * 2 * 5
V = ?

Answer 10

@DustinMHayes And, the answer is .....

Answer 11

20pi ft to thw third power

Answer 12

20 pi cubic feet is what I got, too.
