Question

A cylinder has a base diameter of 8 inches and a height of 7 inches. What is it’s volume in cubic inches

Answer 1

We are given a cylinder

diameter = 8 inches

radius (r) = 8/2 inches = 4 inches

height (h) = 7 inches

Note: The formula for calculating the volume of a cylinder is given by

`Volume=\pi r^2h`

Substituting the parameters

`\begin{gathered} Volume=\pi r^2h \\ Volume=\pi(4)^2(7) \\ Volume=\pi*16*7 \\ Volume=112\pi \\ Volume=351.8583772 \\ Volume=351.8584inches^3 \end{gathered}`

Therefore, the answer is

`Volume=351.8584inches^3`
