Question

ann made a bracelet with a radius of 2 inches. what is the bracelets circumference? round your answer to the nearest tenth. inches

Explanation:

Step1: Recall the circumference formula

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

Step2: Substitute the radius value

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

Step3: Calculate the value and round

$C = 4\pi\approx4\times3.14159 = 12.56636$. Rounding to the nearest tenth gives $12.6$.

Answer:

$12.6$
