p1/p2=V2/V2
but volume is proportional to radius cubed, so
p1/p2=r2^3/r1^3
1/.89 * 17^3cm=R2^3
r2=17 cubrt(1/.89)
Suppose you have a spherical balloon filled with air at room temperature and 1.0 atm pressure; its radius is 17 cm . You take the balloon in an airplane, where the pressure is 0.89 atm.
If the temperature is unchanged, what's the balloon's new radius?
