Please help I don't know why I get the wrong volume. The surface area of a ping pong ball is 7.04 in^2. the surface area of a Baseball is 23.75^2. Find the ratio of the volumes of the two.

Question

My volume is smaller than the radius....

I will give a medal for best answer

$SA=4 \pi r^2\7.04=4 \pi r^2\0.560=r^2\r=0.7486$ (ping pong)
and such the volume 4/3 pi r^3 = 1.757

do the same thing for the other ball

anonymous · Answer

so the volume is 1.757? and the volume can be less than the SA?

bibby · Answer

yeah, I'm trying to logically think about it so I can explain it but I'm too distracted right now

bibby · Answer

ok, so basically you're comparing apples and oranges
surface area is in^2 or whatever
volume is in^3

bibby · Answer

they're entirely different units

anonymous · Answer

alright  so the baseball would be 10.8835?
