Bal-tec - Ball Weight and Density

Ball Weight and Density How much will a ball of a given diameter in a certain material weigh? The answer is calculated by multiplying the volume of the ball by the density of the material. $text"Weight" = text"Volume" ⋅ text"Density"$ For example, calculate the weight of a two inch diameter lead ball: $text"Volume" = {4 ⋅ π ⋅ R^3 }/ 3$
