Answer:
Explanation:
In order to find how much air the balloon will hold, we need to find its volume.
The volume of the ball with radius r is given by
[tex]V=\frac{4}{3}\pi r^3[/tex]Now, in our case r = 13 in /2 = 6.5 in, and therefore,
[tex]V=\frac{4}{3}\pi(6.5)^3[/tex][tex]V=177.0[/tex]which is our answer!
Hence, the ballon will hold 177 cubic inches of air.
