The diameter of a lead ball is 2.1 cm.The density of the lead used is 11.34g/c 3.what is the weight of the ball
Answered by admin @
Solution:-
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
Answer.
