Question

What is the exact volume of a cylinder with a height of 8in and a diameter of 6 in

Answer 1

`72\pi~in.^3`

Explanation:

Use the formula for the volume of a cylinder:

`V = \pi r^2 h`

where r = radius of the base = diameter/2

h = height of the cylinder

`V = \pi r^2 h`

`V = \pi \left((6~in.)/(2) \right)^2 * 8 ~in.`

`V = 8~in\pi (3~in.)^2`

`V = 8~in.\pi (9~in.^2)`

`V = 72\pi~in.^3`

➷ You would use the formula:

volume =
`\pi r^2*h`

Substitute in the values:

(note: the radius is half the diameter)

volume =
`\pi (3)^2*8`

Solve:

Volume = 226.1946711

I'm not sure how far you require it rounded, or if you want the whole value so I will just leave the entire value. If you need assistance with rounding it to specific figures, just comment down below and I'll help.
