Answer 1

21, 35

Explanation:

So you take 3.14 for Pi/π

And you circumference is 65.94

You know that circumference = Pi*Diameter

So you go backwards which is

65.94/3.14

= 21

Ending up with your diameter being 21

Next circumference is 109.9, so you do the same thing going backwards.

109.9/3.14

= 35

So your diameter is 35
