Question

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

Explanation:

Step1: Identify the radius

The radius \( r = 12\) ft.

Step2: Use the circumference formula \(C = 2\pi r\)

Substitute \(r = 12\) and \(\pi=3.14\) into the formula.
\(C = 2\times3.14\times12\)
First calculate \(2\times12 = 24\), then \(24\times3.14\)
\(24\times3.14=(20 + 4)\times3.14=20\times3.14+4\times3.14=62.8+12.56 = 75.36\)

Answer:

\(75.36\)
