Explanation:

Step1: Recall the circumference formula

The formula for the circumference \( C \) of a circle is \( C = 2\pi r \), where \( r \) is the radius. We know \( C = 12.56 \) cm and we can use \( \pi \approx 3.14 \).

Step2: Solve for \( r \)

Rearrange the formula to solve for \( r \): \( r=\frac{C}{2\pi} \). Substitute \( C = 12.56 \) and \( \pi\approx3.14 \) into the formula: \( r=\frac{12.56}{2\times3.14} \). First, calculate the denominator: \( 2\times3.14 = 6.28 \). Then, divide: \( r=\frac{12.56}{6.28}=2 \).
