What is the capacity of a cylindrical tank? | |
I. | Radius of the base is half of its height which is 28 metres. |
II. | Area of the base is 616 sq. metres and its height is 28 metres. |
Answer: Option
Explanation:
I gives, h = 28 m and r = 14.
Capacity = 
r2h, which can be obtained.
Thus, I alone gives the answer.
II gives, r2 = 616 m2 and h = 28 m.
Capacity = (r2 x h) = (616 x 28) m3.
Thus, II alone gives the answer.
Correct answer is (C).
