A sphere of radius 1cm is made from silver. If the mass of the sphere is 33g, find the density of silver (Take π = 3.14).
उत्तर
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" = ("mass of the sphere"("M"))/("Volume of the sphere"("V")`
Density of silver sphere = 7.889 g/cc.
