The volume of a cylinder is equal to the area of the base πr2 times the height.
Substitute the values of the radius r=12 and height h=9 into the formula to find the volume of the cylinder. Pi π is approximately equal to 3.14.
Raise 12 to the power of 2.
Move 144 to the left of π.
Multiply 9 by 144.
The result can be shown in multiple forms.
