62.	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.
	A. I alone sufficient while II alone not sufficient to answer B. II alone sufficient while I alone not sufficient to answer C. Either I or II alone sufficient to answer D. Both I and II are not sufficient to answer E. Both I and II are necessary to answer

Answer:

Answer: Option C

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).
