Question

A sphere of radius 1cm is made from silver. If the mass of the sphere is 33 g, find the density of silver (Take π = 3.14)

Answer 1

Given : radius of a sphere r = 1cm 

Volume of the sphere V = ? 

Mass of the sphere M = 33 g 

Density of silver D = ?

Density D = \(\frac{Mass\, of\,the \,sphere\,(M)}{Volume\,of \, the\,sphere (V}\)

Solution: Density of silver sphere = 7.889 g/cc
