B Correct answer
Explanation

Volume of sphere = (4/3) * pi * r^3. 904.32 = (4/3) * 3.14 * r^3. 904.32 = 4.1866 * r^3. r^3 = 904.32 / 4.1866 = 216. r = cube root of 216 = 6.

AI explanation

The volume of a sphere is calculated using the formula 4/3 times pi times the radius cubed. Setting this equal to the given volume yields the equation 904.32 equals 4/3 times 3.14 times the radius cubed. Simplifying the constants, you get 904.32 equals 4.1867 times the radius cubed, which means the radius cubed is approximately 216. Taking the cube root of 216 gives a radius of 6 centimeters.
