Question

How do I find the volume of a cylinder with a diameter of 20 cm and a height of 15 cm in terms of Pi?

Answer 1

Cylilnder volume formula

$V=\pi\frac{D^2}{4}h$

where D is the diameter and h is the height of the cylinder.

Substituting with D = 20 cm, and h = 15 cm, we get:

$\begin{gathered} V=\pi\cdot\frac{20^2}{4}\cdot15 \\ V=\pi\cdot\frac{400}{4}\cdot15 \\ V=1500\pi\text{ }cm^3 \end{gathered}$
