20ft

To find the circumference of a circle, you can use the formula:

\[
C = \pi \times d
\]

where:
- \( C \) is the circumference,
- \( \pi \) is approximately 3.14,
- \( d \) is the diameter of the circle.

Given:
- \( d = 20 \, \text{ft} \)
- \( \pi = 3.14 \)

Substituting the values into the formula:

\[
C = 3.14 \times 20 \, \text{ft} = 62.8 \, \text{ft}
\]

So, the circumference of the circle is **62.8 feet**.
