What is the exact volume of a cylinder with a radius of 4 in and a height of 8 in.

In the given question it is already given that the radius of the cylinder is 4 inches and the height of the cylinder is 8 inches.

Now

Radius of the cylinder = 4 inches

Height of the cylinder = 8 inches

Value of π = 3.14

Volume of cylinder = π r2 h

Putting the values in the equation we get

Volume of cylinder = 3.14 * 4 * 2 (8)

= 3.14 * 4 * 16

= 200.96 inches^3

So the volume of the cylinder is 200.96 inches^3
