Question

find the circumference.
20 ft
c = ? ft
c = πd = 2πr

Explanation:

Step1: Identify the formula for circumference

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

Step2: Substitute the value of diameter

Given \(d = 20\) ft and using \(\pi=3.14\), substitute into the formula: \(C=3.14\times20\).

Step3: Calculate the result

\(3.14\times20 = 62.8\).

Answer:

\(62.8\)
