Question

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

Explanation:

Step1: Identify the diameter

The diameter \(d = 20\) ft.

Step2: Use the circumference formula \(C=\pi d\)

Substitute \(d = 20\) into the formula. Let \(\pi = 3.14\). Then \(C=3.14\times20\).

Step3: Calculate the result

\(3.14\times20 = 62.8\)

Answer:

\(62.8\)
