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 $textWeight = textVolume ⋅ textDensity$ For example calculate the weight of a two inch diameter lead ball: $textVolume = {4 ⋅ π ⋅ R^3 }/ 3$
