R- the radius of the ball. The volume of a grinding ball is determined by the formula: V=4/3*π*R 3, where: V- the volume of the ball. π — PI constant, a mathematical constant that is equal to the ratio of the circle’s circumference to its diameter. 3.14 is a commonly used value for PI; R- the radius of the ball
