If the amount of air in a spherical balloon is 288 cu. in., what is the radius of the balloon? 6 inches 7.3 inches 72 inches
garik1379 [7]

Answer:

6in

Step-by-step explanation:

The volume of a spherical balloon is 4/3 π R^3.  

So 288π = 4/3 π R^3  

The factors of π cancel out. Divide both sides by 4/3 to get:  

216 cubic inches = R^3  

Take the cube root of both sides, and you find that R = 6 inches
