A cylindrical tank has a capacity of 3080m(^3). What is the depth of the tank if the diameter of its base is 14m?
-
A.
25m -
B.
23m -
C.
22m -
D.
20m
Correct Answer: Option D
Explanation
V = 2080cm(^3), h = ?
r = 7cm
V = V(pi r^2h)
h = (frac{V}{pi r^2} = frac{3080}{frac{22}{7} times 49})
(frac{3080}{54}) = 20cm
