Find the weight of a spherical shell of copper having external diameter and thickness of . Density of copper is .
Step 1: Given information.
External diameter of the spherical shell .
Thickness of ball.
Density of copper.
Step 2: Calculate the volume of the spherical shell.
The external radius of the spherical shell .
The inner diameter of the spherical shell .
So, the inner radius .
Step 3: Calculate the weight of the spherical shell.
The density of copper is .
Hence, the weight of the spherical shell is .
