24. Center of mass A solid of constant density is bounded be-
low by the plane z = 0, on the sides by the elliptical cylinder
x² + 4y2 =
4, and above by the plane z = 2 – x (see the ac-
companying figure).
a. Find x and ỹ.
b. Evaluate the integral
r(1/2)V4-x 2-x
My
z dz dy dx
|-1/2)V4-x²Jo
using integral tables to carry out the final integration with
respect to x. Then divide My by M to verify that 7 = 5/4.
z = 2 - x
x = -2
x² + 4y2 = 4
