Question

A cylinder shaped drum is used to store used motor oil. The drum has a height of 3 ft and a radius of 1.5 ft.

Answer 1

Data:
v (volume) = ?
h (height) = 3 ft
r (radius) = 1.5 ft
Adopting: $\pi \approx 3.14$

Formula:
$V = h* \pi *r^2$

Solving:
$V = h* \pi *r^2$
$V = 3*3.14*1.5^2$
$V = 3*3.14*2.25$
$\boxed{\boxed{V=21.195\:cubic\:feet}}\end{array}}\qquad\quad\checkmark$
