If the capacity of a cylindrical tank is 1848 m3 and the diameter of its base is 14 m, then find the depth of the tank. Pick one:
A) 10
B) 11
C) 12
D) 13
E) none of them

Rationale: let the depth of the tank be h meters . then , ∏ x 72 x h = 1848  h = ( 1848 x ( 7 / 22 ) x ( 1 / 49 ) = 12 m answer is c
Answer: C
