b. 63.4 in
c. 64.1 in
d. 62.8 in

Explanation:

Step1: Recall the circumference formula

The formula for the circumference of a circle is $C = \pi d$, where $d$ is the diameter.

Step2: Substitute the given values

Given $d = 20$ in and $\pi=3.14$, we have $C=3.14\times20$.

Step3: Calculate the result

$C = 62.8$ in

Answer:

D. 62.8 in
