This is a volume problem. You are given the circumference of a beach ball, which is 80 cm.
4%2F3pi%2Ar%5E3
You need to find the radius if you want to solve the problem. Convert the circumference to a radius.
C=2*pi*r
Plug in the circumference of the beach ball to the bottom equation and solve for 4. Plug this r back in to the top equation to get your answer.

Circumference: matrix%281%2C5%2C+2+%2A+pi+%2A+r%2C+so%2C+2+%2A+pi+%2A+r%2C+%22=%22%2C+80%29

matrix%281%2C7%2C+r%2C+or%2C+radius%2C+%22=%22%2C+80%2F%282pi%29%2C+%22=%22%2C+40%2Fpi%29

Volume of sphere = 

Then again, after looking keenly at the problem, 0 (zero) air needs to be added if it's already fully pumped.

I agree! This makes absolutely no sense! Where the H..L do these people get these supposed math problems? Who the H..L writes them?

The question is a nonnsence.


It NEITHER has physical nor mathematical sense.
