Question

the radius of a circle is 14.1 cm. find the circumference to the nearest whole number.

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 given radius

Given $r = 14.1$ cm, so $C=2\times\pi\times14.1$.

Step3: Calculate the value

$C = 2\times3.14159\times14.1\approx88.59$.

Step4: Round to the nearest whole number

Rounding $88.59$ to the nearest whole number gives $89$.

Answer:

$89$
