A cylindrical tank has a capacity of 3080m3. What is the depth of the tank if the diameter of its base is 14m? Take pi = 22/7.
23m
25m
20m
22m
Correct answer is C
Capacity = Volume = 3080m3
base diameter = 14m
radius = diameter2
= 7m
Volume of Cylidner = Capacity of cylinder
πr2h = 3080
227 × 7 × 7 × h = 3080
h = 308022×7
h = 20m
