Question

Height of a cylinder is four times the radius of its base, then the volume of the cylinder is​

Answer 1

Answer:

$4\pi {r}^{3}$

Step by step explanation :

we know that volume of cylinder is

$\pi {r}^{2} h$

now here h = 4r

then volume of cylinder will be

$\pi {r}^{2} (4r)$

and we can write it as

$4\pi {r}^{3}$
