Question

the radius of a circle is 7 inches. what is the circles circumference?
round your answer to the nearest hundredth.
inches

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 \(r = 7\) inches. Substitute \(r\) into the formula: \(C=2\pi\times7\).

Step3: Calculate the value

\(C = 14\pi\). Using \(\pi\approx3.14159\), then \(C\approx14\times3.14159 = 43.98226\).

Step4: Round to the nearest hundredth

Rounding \(43.98226\) to the nearest hundredth gives \(43.98\).

Answer:

\(43.98\) inches
