A Cylindrical hole is drilled through the center of a sphere of radius R. Use the method of cylindrical shells to find the volume of the remaining solid, given that the solid is 6 cm high. Answer : V = 4? ? x ?(R²  x²) dx ..... from ?(R²  (3)²) to R = 4?/3 (R²  x²)^(3/2) ..... from ?(R²  (3)²) to R = 36 ? Are these correct? Thank you

Your answer looks correct, and I again apologize for another mistake in which I claimed that .
