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

Answer:

$Volume=381.7 \,ft^3$

Step-by-step 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:

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