Question

A cylinder has a base diameter of 8ft and a height of 20ft. What is its volume in cubicft, to the nearest tenths place?

Answer 1

It is given that

$\begin{gathered} d=20\text{ so r=}\frac{20}{2}=10 \\ h=20 \end{gathered}$

Volume of cylinder is given by

$V=\pi\times r^2\times h^{}$

So volume of the given cylinder will be

$\begin{gathered} V=3.14\times16\times20 \\ =1004.8 \end{gathered}$

So volume of cylinder is 1004.80 cubic ft.
