HOW TO CALCULATE THE WEIGHT WHEN YOU KNOW THE DIMATER AND LENGTH?

Speaking to the Solid rod, DO YOU KNOW HOW TO CALCULATE THE WEIGHT WHEN YOU KNOW THE DIAMETER AND LENGTH?

Mathematical formula :

Weight= outer diameter x outer diameter x π x length x density/1000000

E.g.:  JZ10F D8x75mm

Under this grade: density is 14.4g/cm3.

Weight=4x4x3.14x75x14.4/1000000≈0.054kg.

Then, you way want to ask how to check cylinder weight?

E.g.: JZ10F D8x4x75mm

Weight=4x4x3.14x75x14.4/1000000 - 2x2x3.14x75x14.4/1000000≈0.041kg.

 Above all, do you know how to calculate now?
