Question

Plz help me I am stuck on this question

Answer 1

The volume of a cylinder is the area of the circular face times the length of the cylinder.

the area of a circular face is
 $A=\pi r^2 = \pi\frac{d^2}{4}$

hence the volume is
$V= \pi r^2 L = \pi \frac{d^2}{4} L$

the Length "L" is 36 in
the diameter "d" is 3 in
