Two spherical balloons are filled with water. The first balloon has a radius of 3 cm, and the second has a radius of 6 cm.

How much more water is in the larger balloon than in the smaller balloon?
Use 3.14 to approximate pi, and express your answer in the hundredths.

Just find difference in volumes.

We know that volume of sphere is V = 4/3 π r³, where π = 3.14. 

So volume of big balloon is 4/3 π (6)³ = 904.32

And volume of small balloon is 4/3 π (3)³ = 113.04

So larger balloon hold 904.32 - 113.04 = 791.28 cm³ more water than smaller balloon.

Answer: 791.28 cm³
