Question

What is the volume of a cylinder that has a radius of 16m and height of 8m?

Answer 1

Remember that the formula for the volume of a cylinder is:

`V=\pi r^2h`

Where:

• r, is the radius of the base

,

• h, is the height of the cylinder

Notice that we're given the diameter, and that the radius is one half of the diameter. Thereby, the radius of the base would be 8m

Using this, the height given and the formula, we'll get that

`\begin{gathered} V=8^2\cdot8\pi\rightarrow V=8^3\pi \\ \Rightarrow V=512\pi \end{gathered}`

The volume of the figure is

`512\pi`
