Correct answer
Explanation
Volume = (4/3) * pi * r^3. Volume = (4/3) * (22/7) * 7 * 7 * 7 = (4/3) * 22 * 49 = 4312 / 3 = 1437.333 = 1437 1/3.
AI explanation
The formula for the volume of a sphere is four thirds times pi times r cubed. Substituting the radius of 7 cm gives four thirds times 22 divided by 7 times 7 cubed, which simplifies to four thirds times 22 times 49. This calculation results in a volume of 4312 divided by 3, or 1437 and one third cubic cm. The result is 1437 and one third.
