Give answer :

(Applicable only to the following question)

What is the curved surface area of the right circular cylinder

I.Area of the base of the cylinder is 616 cm²

II.Volume of the cylinder is 9240 cm²,

If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
If the data either in statement I alone or in statement II alone are sufficient to answer the question.
If the data given in both statements I and II together are not sufficient to answer the question.
If the data in both statements I and II together are necessary to answer the question.
Explanation:

I. Given,

πr²= 616 cm²

22/7×r²=616

r²=616×7/22

r=14cm

II. Given, πr²h=9240

22/7×14×14×h = 9240

h = 420/28

h = 15 cm

Now, curved surface area of the cylinder = 2πrh

= 2×22/7×14×15 = 1320 cm²

Hence, the data in both statement I and II together are necessary to answer the question.
