Question

Find the volume of a sphere that has a surface area of 16 sq. in.

Answer 1

area of sphere is 4(pi)(r^2). you know surface area, and everything is constant, but r. so get positive r from this eqn. Then you know that the volume is V= 4(pi)(r^3)/3, sub that positive r to get volume.

Answer 2

Im confused...

Answer 3

I know the area of a sphere but I don't understand the rest of what you said. haha sorry

Answer 4

this question has one sub question in it. it is to get radius r from the given surface area. Surface area= 4(pi)r^2=16. get r.

Answer 5

oh! ok! thank you for!

Answer 6

after you have solved for r, you can get volume right?

Answer 7

yes I believe the volume is \[\frac{ 32 }{ 3 }\] times pi
