Answer: 10 / pi
Explanation:
V = pi * r^2 * h (basically just stacking an circle of area pi * r^2 on top of each other h times, this addition of area is the volume)
1210 = pi * (22 / 2)^2 * h (since 22 is diameter, 22 / 2 = radius)
Solved the equation for h:
1210 / 121 = pi * h
10 / pi = h, thus we find our answer
