Question

Find the volume of a cylinder. Leave your answer in terms of π.

Answer 1

Given figure of cylinder with height 8cm and diameter 8cm.

Volume of cylinder

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

We have given diameter = 8 cm

So, radius

`=(Diameter)/(2)`

Radius

`\begin{gathered} =(8)/(2) \\ =4 \end{gathered}`

Now, volume of cylinder

`\begin{gathered} =3.14*4^2*8 \\ =3.14*16*8 \\ =401.92 \end{gathered}`

Hence, volume of cylinder is 401.92 centimetre cube.
