B Correct answer
Explanation

Volume of sphere = 4/3 * pi * r^3 = 4/3 * 3.14159 * 7^3 = 4/3 * 3.14159 * 343 = 1436.755. Closest value is 1437.33.

AI explanation

The volume of a sphere is calculated using the formula V equals 4/3 times pi times r cubed. Substituting the radius of 7 cm into the formula gives 4/3 times 22/7 times 7 cubed, which simplifies to 4/3 times 22 times 49. Multiplying these values gives 4312 divided by 3, resulting in a volume of approximately 1437.33 cubic centimeters.
