AI explanation

Using the sphere volume formula of (4/3) * pi * r^3 with a radius of 14 cm and pi approximated as 22/7, the volume is (4/3) * (22/7) * (14)^3, which equals 34496 cubic cm. Using the surface area formula of 4 * pi * r^2, the calculation is 4 * (22/7) * (14)^2, yielding 2464 square cm. These calculations match the volume of 34496 and surface area of 2464.
