V = [tex] \pi \pi [/tex][tex] r^{2}[/tex]h

1. Find the radius. 

8/2 = 4

2. Square the radius.

[tex] 4^{2} [/tex] = 16

3. Multiply that by pi.

3.14 * 16 = 50.24

4. Multiply that by the height.

50.24 * 20 = 1004.8

5. Now find 60% of that.

1004.8 * 0.6 = 602.88

V = 602.88 [tex] m^{3}[/tex]

Honestly, it's been a while since I've done this, but I believe this is the answer.
