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

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

120 inches cubed (^3)

To find the volume of a rectangular prism, the formula is base area • height. We just have to solve this problem.

The two sides of the base 8 and 5.    8 • 5 = 40, so the area of the base = 40.

Then, the height is 3.    40 • 3 = 120, so the volume is 120 inches^3
