Chapter 5.3, Problem 162E

a. Find the volume of the solid S1 bounded by the cylinder $x^2+y^2=1$ and the planes z = 0 and

b. Find the volume of the solid S2 outside the double cone $z^2=x^2+y^2$. inside the cylinder $x^2+y^2=1$ . and above the plane z = 0.

c. Find the volume of the solid inside the cone A) A) A) $z^2+x^2+y^2$ and below the plane z = 1 by subtracting the volumes of the solid $S_1$ and $S_2$.
