A cylindrical hole of radius r is made in a sphere of radius "a" so that the axis of the cylinder coincides with a diameter of the sphere.
Find the volume that remains.[Hint: with the diameter as y axis,take an element of area 2ydelta x and use Pappus Theorem]
Please can you help.
Thank you.
Rest assured the hint is not from me,it is from the book.
