Step1: Recall circumference formula

The formula for the circumference \( C \) of a circle is \( C = \pi d \), where \( d \) is the diameter. Here, \( d = 5 \) cm.

Step2: Substitute and calculate

Substitute \( d = 5 \) into the formula: \( C=\pi\times5\approx3.14\times5 = 15.7 \) cm.

Answer:

C. 15.7 centimeters
