h=Hr=3

The volume of a cylinder is equal to the area of the base πr2 times the height.

π⋅(radius)2⋅(height)

Substitute the values of the radius r=3 and height h=H into the formula to find the volume of the cylinder. Pi π is approximately equal to 3.14.

π⋅32⋅H

Raise 3 to the power of 2.

π⋅9⋅H

Move 9 to the left of π.
