To find the circumference \( C \) of a circle, you can use the formula:
\[
C = \pi \times d
\]
where \( d \) is the diameter of the circle. Given that the diameter is 20 inches, we can substitute this value into the formula:
\[
C = \pi \times 20
\]
In terms of \(\pi\), the circumference is:
\[
C = 20\pi \text{ inches}
\]
To estimate the circumference, we can use an approximate value for \(\pi\) (about 3.14):
\[
C \approx 20 \times 3.14 = 62.8 \text{ inches}
\]
Therefore, the circumference of the circle is \( 20\pi \) inches in terms of \(\pi\), and approximately \( 62.8 \) inches.
