1. The problem statement, all variables and given/known data By using cylindrical coordinates , evaluate the volume of solid bounded on top of sphere (x^2) + (y^2) + (z^2) = 9 and it's sides by (x^2) + (y^2) = 4x . 2. Relevant equations 3. The attempt at a solution I have sketched out the diagram , but i dun know which part is the solid formed.... Can someone highlight the solid formed ?
