KaranSingh - Please make sure to post the full questions - in separated posts and include the full answers. Otherwise you are hurting the other people's practice.
Good luck tomorrow.

Answer 1:
TIP (not related to this question directly) - given two sizes to choose from - a cylinder will have more volume if the bigger number is it's radius and not his height. (surface of the base is squared and height it not).

now - about question number 1 - few steps to follow -
radius 5 means that the diagonal is 10. therefore - the base can be ONLY the face with the 10*12 dimension.
all the other positions will not be able to hold a circle with radios of 5.
so - the height is 8.
(remember - cylinder's volume = the base's surface*height).
therefore:
base surface - Pie*r^2 = Pie * 25
Height is 8
so the full answer would be - 8*25*pie = 200*pie.

Question number 2 is not clear to me and it will be helpful if you post the answers.
