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
They created ratios so people could get information.
The correct answer would be C
