The diameter of a circle measures 20 ft. What is the circumference of the circle?Use 3.14 for π, and do not round your answer. Be sure to include the correct unit in your answer.

Step 1:

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

Step 2:

Given the diameter \(d = 20\) ft and using \(\pi = 3.14\):

\(C = 3.14 \times 20 = 62.8\) ft.

Supplemental Knowledge:

The circumference of a circle is the distance around its edge. The formula to calculate the circumference when you know the diameter is: 
\[\text { Circumference} = \pi \times \text { diameter} \]

Given that the diameter (\(d\)) of the circle is 20 feet, we can use this formula to find the circumference.

Applied Knowledge:

Imagine you are planning to install a 20-foot diameter circular walking path around a park, knowing its circumference will enable you to determine how much material will be required for edging or how long it will take you to walk around it.
