Answer: b.

125.6 in.

Step-by-step explanation:

We know that the circumference of a circle is given by :_

[tex]\text{Circumference}=2\pi r[/tex], where r is the radius of the circle.

Given : The radius of the circle : r= 20 i.

Then , the circumference of the circle is given by :-

[tex]\text{Circumference }=2(3.14)(20)\\\\\Rightarrow\ \text{Circumference }=125.6\ in.[/tex]

Hence, the circumference of the circle = 125.6 in.
