Calculate the height of the rotating truncated cone with volume V = 1115 cm3 and a base radii r1 = 7.9 cm and r2 = 9.7 cm.
Leave us a comment of example and its solution (i.e. if it is still somewhat unclear...):

it's formula; can be proved....https://math.stackexchange.com/questions/1626218/calculation-of-rise-in-height-of-water-in-a-frustum-of-right-circular-cone
can u explain why you do (r2 + rxR + R2) in the first step

Fine math problem! Go ahead!
but to prove formula, you need to know how to solve integral
need to solve a cubic equation, as obtained above, to find rises in heights... integral
To solve this example are needed these knowledge from mathematics:
