Discussion Forum : Volume and Surface Area - Data Sufficiency 2 (Q.No. 1)

*Directions to Solve*

Each of the questions given below consists of a question followed by three statements. You have to study the question and the statements and decide which of the statement(s) is/are necessary to answer the question.

1.

What is the capacity of the cylindrical tank? | |

I. | The area of the base is 61,600 sq. cm. |

II. | The height of the tank is 1.5 times the radius. |

III. | The circumference of base is 880 cm. |

Answer: Option

Explanation:

Capacity = *r*^{2}*h*.

I gives, *r*^{2} = 61600. This gives *r*.

II gives, *h* = 1.5 *r*.

Thus, I and II give the answer.

Again, III gives 2*r* = 880. This gives *r*.

So, II and III also give the answer.

Correct answer is (E).

Using one and three we can be able to find only the radius.

So, using 2 can get h that is h=1.5r after getting height we can substitute in 1 or 3 and then finally we can substitute all in capacity.

So, using 2 can get h that is h=1.5r after getting height we can substitute in 1 or 3 and then finally we can substitute all in capacity.

Answer can't be D since I and III can't give the volume. Both gives the radius. We need height for volume.
