Question

the radius of a circle is 19 centimeters. what is the circles circumference? round your answer to the nearest hundredth. centimeters

Explanation:

Step1: Write 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 \(r = 19\) cm. Substitute \(r\) into the formula: \(C=2\times\pi\times19\).

Step3: Calculate the value

\(C = 38\pi\approx38\times3.1415926 = 119.3805188\).

Answer:

\(119.38\) centimeters
