Answer: 
Step-by-step explanation:
1. To solve this problem you must use the following formula for calculate the volume of a right circular cylinder, which is shown below:

Where r is the radius and h is the height.
2. Now, you must substitute the values given in the problem. Therefore, you obtain the following result:


the sum of supplementary angles is 180 degree
therefore
x +2x = 180°
3x = 180
X = 180/3 = 60°
the value of X is 60°
