I'm confused with how to solve this problem, so help would be great!

The volume of any spherical balloon can be found by using the formula V= 4/3 pi r^3. Write an equation for r in terms of V and pi

4/3*pi*r3 = V
Multiply by 3
3*(4/3)*pi*r3 = 3*V
4*pi*r3 = 3V
r3 = 3V/(4*pi)
r = [3V/4pi]1/3
I hope all of this comes out ok. Check my work.

thanks for your help. :)
