the diameter of a lead ball is 2.1cm.the density of the lead used is 1

1.	the diameter of a lead ball is 2.1cm.the density of the lead used is 11.34g/c^3 what is the weight of the ball. Answer : 5.5kg
Answer» Given : Diameter of the ball = 2.1 cm or radius = 2.1/2 = 1.05 cm Volume of the Spherical lead ball = 4/3πr³= 4/322/71.051.051.05 Volume of the lead ball = 4.851 cu cm Lead used for making lead ball = 11.34 g/cu cm So, the weight of the lead ball = 11.34× 4.851 Weight of the lead ball = 55.01 grams thankyou

Answer»

Given : Diameter of the ball = 2.1 cm or radius = 2.1/2 = 1.05 cm

Volume of the Spherical lead ball = 4/3πr³= 4/3*22/7*1.05*1.05*1.05

Volume of the lead ball = 4.851 cu cm

Lead used for making lead ball = 11.34 g/cu cm

So, the weight of the lead ball = 11.34× 4.851

Weight of the lead ball = 55.01 grams

thankyou
