I believe you only need to know one angle.
For example, if you know angle 1, you can calculate angle 3. Angle 2 = angle 3 and angle 4 = angle 1.
Also, Angle 5= angle 1 and so on...
Solution:
we have been asked to find
The expression is equivalent to 
we can simplify the given expression as below

Hence the simplified expression , equaivalent to the given expression is 1/2.
V solid = π *

* 13 / 3 + π *

* 2 = 3.14 * 25 *13 / 3 + 3.14 * 50 = 340.16 + 157 = 497.16 ≈ 497.20 cubic centimeters;
