h=7mr=3m

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=3 and height h=7 into the formula to find the volume of the cone. Pi π is approximately equal to 3.14.

13⋅π⋅32⋅7

Combine 13 and π.

π3⋅32⋅7

Raise 3 to the power of 2.

π3⋅9⋅7

Factor 3 out of 9.

π3⋅(3(3))⋅7

Cancel the common factor.

π3⋅(3⋅3)⋅7

Rewrite the expression.

π⋅3⋅7

π⋅3⋅7

Move 3 to the left of π.

3⋅π⋅7

Multiply 7 by 3.
