the circumference of a circle is 28 in.
what is the diameter of the circle?
\\( \frac { 28 } { \pi } \\) in.
\\( \frac { 14 } { \pi } \\) in.
\\( \sqrt { \frac { 28 } { \pi } } \\) in.
\\( \sqrt { \frac { 14 } { \pi } } \\) in

Explanation:

Step1: Recall the formula for circumference

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

Step2: Solve for the diameter

Given \(C = 28\) in, we substitute into the formula \(28=\pi d\). Then, solving for \(d\), we get \(d=\frac{28}{\pi}\) in.

Answer:

\(\frac{28}{\pi}\) in (the first option)
