I would like to ask how to solve the question. It is a question from multivariable calculus. thank you

5. (10 marks] Suppose R — r0 > 0 and we assume both r0 andR are positive. We remove a central cylinder of radius r0 from a sphere of radius R. Show, W that the resulting volume of the remaining portion of sphere is k[(R + T0)(R — r0)]2 , where k is a constant. Show the value of the constant kexplictly in your final answer. (Hint: Without loss of generality, we may simply assume that the sphere is centered at the origin.)1
