Question

A solid has a radius of 2cm and of 0.05kg. What is rhe relative density of the sphere

Answer 1

Hey friend!!!
Relative density = Mass/Volume
0.05kg = 50 g
Volume = 4/3 pie r^3
= 4/3×22/7×2×2×2
Relative density =50/4/3×22/7×8
= 1.49
Hope it helps u!!!

Answer 2

Answer:

Radius of sphere=2cm =2/100=0.02 m

Volume of the sphere=4/3

$\pi$

r³

=4/3× 22/7×0.02×0.02m³=0.000704/21 m³

Mass of sphere=0.05kg.

Relative density of sphere=density ×10³

=0.05/0.000704\21 ×10

=0.05×21/704×10-6×10³

=1.05×10³/704×10-6

=1.05×10³±6/704=1.05×109/704=1.49×106

Relative density of sphere= 1.49×106 kg/m³
