Find the inner diameter of the washer.
atroni [7]

The inner diameter of the washer is 7/10 inch, this value is gotten by multiplying the path by 2 and subtracting the result from the outer diameter

<h3>Mensuration of Shapes</h3>

Given Data

  • Outer Diameter = 1 inch
  • Path Distance = 3/20 inch

The inner diameter

= Outer Diameter - 2*Path Distance

= 1 - 2*3/20

= 1- 6/20

= 1- 3/10

= 1/1 - 3/10

Find the LCM we have 10

= 10-3/10

= 7/10 inch
