Step-by-step explanation:
Your answer is: 128 pi.
pi x 4^2 x 8
pi x r ^2 x h
The segment marked 20 is the geometric mean of the two pieces into which it splits the hypotenuse. You get the proportion

Solving,

To find b, use the fact that b is the geometric mean of the whole hypotenuse, 21 + a, and the part that is attached to it, a.

A little arithmetic shows that

.
