Question

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

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given radius

Given $r = 2$ feet, we substitute into the formula: $C=2\pi\times2 = 4\pi$.

Step3: Calculate the value and round

Using $\pi\approx3.14159$, we have $C\approx4\times3.14159 = 12.56636$. Rounding to the nearest hundred - th, $C\approx12.57$.

Answer:

$12.57$
