Question

the daimeter of a lead ball is 2.1cm. The Density Of the Lead used is 11.34g/c³. What is The Weight of the ball

Answer 1

$\huge\mathbb\blue{ANSWER:-}$

Step-by-step explanation:

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
