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 = πr2h
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
