answer attempt 1 out of 2
c = □ in submit answer

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 value of radius

Given \(r = 2.5\) in. Substitute into the formula: \(C=2\pi\times2.5\).

Step3: Calculate the value

\(C = 5\pi\). Using \(\pi\approx3.14\), we get \(C\approx5\times3.14 = 15.7\) in.

Answer:

\(15.7\)
