What is the volume of 32 metre high cylindrical tank? | |
I. | The area of its base is 154 m2. |
II. | The diameter of the base is 14 m. |
Answer: Option
Explanation:
Given, height = 32 m.
I gives, area of the base = 154 m2.
Volume = (Area of the base x Height) = (154 x 32) m3.
Thus, I alone gives the answer.
II gives, radius of the base = 7 m.
Volume =  r2h |
= |  |
22 | x 7 x 7 x 32 |  m3 |
= 4928 m3. |
| 7 |
Thus, II alone gives the answer.
Correct answer is (C).

I think A would be the right Answer because here it's asked about the Volume of the cylindrical tank not about the cuboid.
