The area shown is revolved about the x axis to form a homogeneous solid of mass m. Approximate the area using a series of 400 rectangles of the form each of width ?l, and then write a computer program that can be used to determine the mass moment of inertia of the solid with respect to the x axis. Use this program to solve part a of (a) Sample Prob. 9.11, (b) Prob. 9.121, assuming that in these problems m = 2 kg, a = 100 mm, and h = 400 mm.
