Check Answer @ Question 13 ~Mo/1pt O3 @ Details Find the volume of the solid bounded below by the plane z = 4 and above by the sphere x4+ y2 + 22 =72, Write your answer as a reduced fraction. Volume = 7 Step 1: The integral can be evaluated as, ( pcos ($)) (p'sin ($)) apdead = " (p'sin ($)cos ($)) apdead -S. S." [ e" sin (p )cos ( ) dead -1.
