Question

The radius of cylindrical water tank is 4.5 ft, and its height 6 ft, What is the volume of the tank?

Answer 1

`Volume=381.7 \,ft^3`

Explanation:

Use the formula for the volume of a cylinder:

Volume= B times height

Being "B" the area of the cylinder's base (a circle of radius 4.5 ft.

Therefore the area of the base is:

`Area=\pi R^2 = \pi (4.5\,ft)^2=63.617\,ft^2`

So the volume of the cylinder is:

`Volume=B\,*\,h = 63.617\,* 6\,ft^3=381.7 \,ft^3`
