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.
