The answer is 26.36. If you were trying to figure out what is 25% of 6.59, you'd have to multiply, however you need to know what 6.59 is 25% of so you do the opposite, just divide 6.59 by .25 and you'll get 26.36 which is your answer.
I cup = 8 fl oz

Hope this helps.
V=4/3*pi*r³;
Balloon A (3cm) has a volume of 113.1.
Balloon B (6cm) has a volume of 904.78.
Then you do 904.78-113.1, to get 791.68 cm³
