| 1. To solve this problem, we need knowledge of the following formulas:

The volume of the ball can be calculated by the formula: V = 4/3 * π * R ^ 3, R is the radius of the ball,

V is the volume of the sphere, π – 3.14.

2. Now let’s find the volume of the ball, for this we substitute the quantities known to us, such as its radius is 3.5 cm into the formula for the volume of the ball, then we get:

V = 4/3 * π * R ^ 3 = 4/3 * 3.14 * R ^ 3 = 4/3 * 3.14 * 3.5 ^ 3 cm = 4/3 * 3.14 * 42.875 cm ^ 3 =

= 4/3 * 134.6275 cm ^ 3 = 179.5 cm ^ 3.

Answer: the volume of the ball is 179.5 cm ^ 3.
