Hi,

This problem could have been solved, if we knew that the sides 6 and 8 are the legs of the right angled triangle. But, since that is is not mentioned, the answer can not be determined.

Hence, the answer is (A).

This answer is very rare on the GMAT.

Hi
You are right that "Can not be determined" option is generally not correct in PS Question, But we must be aware that it can be correct also. So We must read all the options with an open mind.

Hi,

I'm wondering how we can determine the area of a circle equals to 10pi?

Hi DarleneTran,
Its NOT 10\(\pi\) its " Cannot be determined ", you probably got confused with option B.
