How do I find the volume of a sphere in terms of pi?

the formula for a sphere is 3/4pi r cubed So if the radius was 3 then u would multiply 3 times 3 times 3 and u get 27 Then u multiply 27 by 4 which in this case is 108 then divide 108 by 3 and u get 36 So in terms of pi, the answer would be 36*pi
