Find the area and volume of a sphere whose diameter is 10 cm.

To complete the task, we find the radius of the ball, which is equal to half the diameter:
R = 1/2 * D = 5 (cm).
The surface area and volume of the sphere are calculated by the formulas:
S = 4 * π * R² = 4 * 3.14 * 25 = 314 (cm²).
V = 4/3 * π * R³ = 4/3 * 3.14 * 125 = 523.333333 ≈ 523.33 (cm³).
Answer: the surface area of the ball is 314 cm², the volume of the ball is 523.33 cm³.
