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)
A
23 m
B
25 m
C
20 m
D
22 m
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
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/(22x7)
h = 20 m
