A cylindrical tank has a capacity of 3080 m³. What is the depth of the tank if the diameter of its base is 14 m?
(Take pi = 22/7)

Correct Answer: Option C

Explanation

Capacity = 3080 m³
Base diameter = 14 m, thus radius = 7 m.
Volume of cylinder = capacity of cylinder = πr²h. = 3080
22/7 x 7² x h = 3080
h = 3080/(22×7)
h = 20 m
