V=4/3 pi r^3 is correct
using 22/7 for pi
I get 7241.143 cubic inches
in cubic feet it would be
4/3pi*1^3 (since 12in=1ft)
4.19 cubic feet

Your formula for volume appears to be correct but you would need to know the pressure to which the ball is inflated as the free air used is being compressed.

i got 4.1887902047863909846168578443727 ft cubed
and 7238.229473870883621417930355076 in cubed
dont think you need all the decimal places.. but just in case.
4/3 is 1_1/3.
12 in is 1 ft.
1 cubed is 1.
1.33333333333333333333333333333333 *
3.1415926535897932384626433832795 * 1 = 1st number shown above.

V = (4 Pi/3)r3 = (Pi/6)d3
[4(3.14)]/3 times 12(12)(12)
(12.56/3) 1728
4.19(1728) = 7240.32

12 in.=1ft
V=4/3*22/7*1^3
V=4/3*22/7*1
v=4.19 ft^3

I would rather hear you say "Please" and "Thank you" than give me 5 points.
