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=}(20)/(2)=10 \\ h=20 \end{gathered}`

Volume of cylinder is given by

`V=\pi* r^2* h^{}`

So volume of the given cylinder will be

`\begin{gathered} V=3.14*16*20 \\ =1004.8 \end{gathered}`

So volume of cylinder is 1004.80 cubic ft.
