Question

the radius of a circle is 5.8 in. find the circumference to the nearest whole number.

Explanation:

Step1: Recall the formula for the circumference of a circle

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

Step2: Substitute the given radius into the formula

Given \(r = 5.8\) in, we substitute into the formula: \(C=2\pi\times5.8\).

Step3: Calculate the value

\(C = 2\times3.14\times5.8= 36.424\) in.

Step4: Round to the nearest whole number

Rounding \(36.424\) to the nearest whole number gives \(36\) in.

Answer:

\(36\) in
