Question

the radius of a circle is 2 inches. what is the circles circumference? round your answer to the nearest hundredth.

Explanation:

Step1: Recall circumference formula

The formula for the circumference of a circle is $C = 2\pi r$.

Step2: Substitute radius value

Given $r = 2$ inches, so $C=2\pi\times2 = 4\pi$.

Step3: Calculate and round

$C\approx4\times3.14159 = 12.56636\approx12.57$ inches.

Answer:

$12.57$ inches
