Answer:

r = 35.18 mm

Step-by-step 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=\dfrac{D}{2}\\\\r=\dfrac{70.36 }{2}\\\\r=35.18\ mm

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

Hey there! :D

So, we know that there are 3 z's and 3 6's. 

3*z= 3z

6*3= 18 

3(z+6) <== equivalent expression 

3z+18 <== equivalent expression

z is by itself. It shouldn't combine. It should stay the same. 6 as a unit is separate from z. 

Choices "B" and "E" are correct.

I hope this helps!
