Verified Answer :

C= 2πr
C= 2 x 3.14 x 20
C = 125.6

answer: 
b. 125.6 in.

Answer: b.

125.6 in.

Step-by-step explanation:

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

\(\text{Circumference}=2\pi r\), 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 :-

\(\text{Circumference }=2(3.14)(20)\\\\\Rightarrow\ \text{Circumference }=125.6\ in.\)

Hence, the circumference of the circle = 125.6 in.
