h=7cmr=4cm

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=4 and height h=7 into the formula to find the volume of the cone. Pi π is approximately equal to 3.14.

13⋅π⋅42⋅7

Combine 13 and π.

π3⋅42⋅7

Raise 4 to the power of 2.

π3⋅16⋅7

Combine π3 and 16.

π⋅163⋅7

Move 16 to the left of π.

16⋅π3⋅7

Combine 16π3 and 7.

16π⋅73

Multiply 7 by 16.
