Question

The surface area of the figure below is 100% cm. Find the volume in terms of n

Answer 1

I’m not sure if this is what you meant but since you know the surface area of a sphere is 4 Pi r ². You can work backwards and do the opposite (ex: subtraction for addition)
This can help you get the radius as the answer. Since the volume of a sphere is 4/3 Pi r ², just plug in the radius.
