Question

what is the volume of the right circular cylinder with a diameter of 10 meters and a height of 16 meters. leave the answer in terms of pi.

Answer 1

Answer: The answer is A, 400π m3

Explanation:

Answer 2

if it has a diameter of 10, that means its radius is half that or 5.

`\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=5\\ h=16 \end{cases}\implies V=\pi (5)^2(16)\implies V=400\pi`
