Question

3. Find the volume of each of the following cylinders.

a. r = 3 inches, h = 3 inches
b. r = 1 meter, h = 4 meters

Answer 1

a.12.56

b.84.82

Explanation:

you have to do 3 * 3 * π * 3 and you get 12.56

with b you have to do π * 1 * 1 * 4 and you will get 84.82

Answer 2

a.
`V=84.82\ in^3`

b.
`V=12.57\ in^3`

Explanation:

The formula for calculating the volume of a cylinder is the following:

`V=\pi r^2h`

Where r is the radius of the cylinder and h is the height of the cylinder

So for the first cylinder we have to:

r = 3 inches, h = 3 inches

`V=\pi (3)^2(3)`

`V=27\pi`

`V=84.82\ in^3`

For the second cylinder we have to:

r = 1 meter, h = 4 meters

`V=\pi (1)^2(4)`

`V=4\pi`

`V=12.57\ in^3`
