Question

A flat circular plate of copper has a radius of 0.131 m and a mass of 98.6 kg. What is the thickness of the plate? Answer in units of m.

Answer 1

h = 0.204 m

Step-by-step explanation:

given data:

radius r = 0.131 m

mass m = 9.86 kg

density of copper = 8960 kg/m3

we knwo that density is given as

`\rho = (mass)/(volume)`

`volume = \pi * r^2 h`

`density  =  ( mass)/(\pi * r^2 h)`

`h = ( mass)/(\pi * r^2 * density)`

putting all value to get thickness value

`h = ( 98.6)/( \pi 0.131^2*8960)`

h = 0.204 m
