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 = *r*^{2}*h*, which can be obtained.

Thus, I alone gives the answer.

II gives, *r*^{2} = 616 m^{2} and *h* = 28 m.

Capacity = (*r*^{2} x *h*) = (616 x 28) m^{3}.

Thus, II alone gives the answer.

Correct answer is (C).
