Question

the diameter of a circle is 151 m. find the circumference to the nearest whole number.

Explanation:

Step1: Recall the formula for circumference.

The formula for the circumference $C$ of a circle is $C = \pi d$, where $d$ is the diameter.

Step2: Substitute the given diameter.

Given $d = 151$ m, so $C=\pi\times151$.
Using $\pi\approx3.14159$, we have $C\approx3.14159\times151$.
$C\approx474.37009$.

Step3: Round to the nearest whole number.

Rounding $474.37009$ to the nearest whole number gives $474$.

Answer:

$474$ m
