Answer 1

A solid sphere has a radius of 2cm and
a mass of 0.05kg. what is the relative
density of the sphere? Answer: 1. Ajeet.
1 year ago. Volume v=4/3 πr^3 =(4/3)×
3.14×8×10^-6 =33.49×10^-6.
Density=mass/volume

Answer 2

Volume of sphere = 4πr³/3
= 4 × 3.14 × (2 cm)³ / 3
= 33.5 cm³

Density = Mass / Volume
= 50 g / 33.5 cm³
= 1.5 g/cm³

Relative denisty = Density of substance / Density of water
= (1.5 g/cm³) / (1 g/cm³)
= 1.5

∴ Relative density of sphere is 1.5
