Question

The diameter of a reamed hole is 70.36 mm. What is the radius setting, in mm., used to draw the hole?

Answer 1

r = 35.18 mm

Explanation:

We have,

The diameter of a reamed hole is 70.36 mm.

It is required to find the radius required to draw the hole.

The relation between diameter and radius is given by :

D = 2r

r is radius setting

`r=(D)/(2)\\\\r=(70.36 )/(2)\\\\r=35.18\ mm`

So, the radius setting used to draw the hole is 35.18 mm.
