Question

find the circumference of the circle if you have a radius of 18.2 cm. use 3.14 for π. round to the nearest whole

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 values

Given \(r = 18.2\) cm and \(\pi=3.14\), substitute into the formula: \(C = 2\times3.14\times18.2\).
First, calculate \(2\times3.14 = 6.28\). Then, \(C=6.28\times18.2\).

Step3: Round to the nearest whole number

Since \(114.296\approx114\) (because the decimal part \(0.296\lt0.5\)).

Answer:

\(114\)
