Question

Find the volume of this cylinder.


`v = \pi {r}^(2) h`

Hint: Plug in the value of r. The diameter is 8. The radius is half this value.​

Answer 1

r = 4

h = 20

V = 960
`cm^(3)`

Explanation:

The radius is half of the diameter. Half of 8 is 4.

Volume = π ·
`radius^(2)` · height

v = π ·
`(4)^(2)` · 20

V = 3 · 16 · 20

V = 960
`cm^(3)`
