Please help with these two problems. Thank you!
A sphere of radius r is generated by revolving the graph of y = root r2 - x2 about the x-axis. Verify that the surface area of the sphere is 4pir2. Find the volume left over after a sphere of radius R has a hole of radius 1/2 R drilled through the center.
