Question

The volume of this cylinder is 2880π cm3.

Find the length of the radius, r.
Give your answer as a surd in its simplest form.

Answer 1

Explanation:

`volume \: of \: cyinder = \pi{r}^(2)h \\ \pi {r}^(2) * 120cm = 2880\pi {cm}^(3) \\ {r}^(2) = 24 \: {cm}^(2) \\ r = √(24) \: = 4.899 \: cm`
