Question

the diameter of a circle measures 20 cm. what is the circumference of the circle? use 3.14 for π, and do not round your answer. be sure to include the correct unit in your answer.

Explanation:

Step1: Recall circumference formula

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

Step2: Substitute given value

Given $d = 20$ cm and $\pi=3.14$, we have $C=3.14\times20$.

Step3: Calculate result

$3.14\times20 = 62.8$ cm.

Answer:

$62.8$ cm
