h=13r=9

The volume of a cone is equal to 13 times the area of the base πr2 times the height h.

13⋅π⋅(radius)2⋅(height)

Substitute the values of the radius r=9 and height h=13 into the formula to find the volume of the cone. Pi π is approximately equal to 3.14.

13⋅π⋅92⋅13

Combine 13 and π.

π3⋅92⋅13

Raise 9 to the power of 2.

π3⋅81⋅13
