Question

If the amount of air in a spherical balloon is 288xpi cu. in.,

what is the radius of the balloon?

Answer 1

now we are talking dude :)

Answer 2

the amount of air represents the volume of the sphere,
and the volume of the sphere is given by :\[v=4/3 \pi r^3 \rightarrow 288*\pi =4/3*\pi*r^3 \rightarrow r^3=\frac{ 3*288 }{4 }\rightarrow r=\sqrt[3]{216}=6\]

Answer 3

thanks!:) you've been a lot of help!

Answer 4

even though this is not 100% right :P , but still you are welcome :)
