Answer 2

ohh hmm actually that'd be the volume ...

anyohw... yes, you're right, is \(\bf 4\pi r^2\)

Answer 3

It's surface area = 3*pi*r^2. So you just substitute your r with 8 and solve it out.

Answer 4

Yes yes, you're right teenah.

Answer 5

My written formula was for the surface area of a HEMISPHERE.

Answer 6

Yes, hee.
