Question

the radius of a circle is 14.2 in. find the circumference to the nearest tenth.

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 \(r=14.2\) in. Substitute into \(C = 2\pi r\), we get \(C = 2\times\pi\times14.2\).

Step3: Calculate the value

\(C=2\times3.14\times14.2\) (using \(\pi\approx3.14\))
\(C = 6.28\times14.2\)
\(C=89.176\)

Answer:

\(89.2\) in.
