Answer 2

i think it would be A

Answer 3

A, because a circle's area is...\[\pi r ^{2}\]

If you were to stretch that circle up into a cylinder you are basically multiplying by the height hence....\[\pi r ^{2} h\]

Answer 4

Also don't forget since it's 3 dimensional, it will be measured in cubic units.

Answer 5

its multiple choice

Answer 6

I know, but for future reference :)

Answer 7

so what other answer is it

Answer 8

A :)

Answer 9

A and

Answer 10

Oh sorry and for the spherical ball that would be...\[\frac{ 4 }{ 3 }\pi r ^{3}\]

Answer 11

so A and C. My apologies I didn't read the question properly.
