Question

the diameter of a circle is 71 m. find the circumference to the nearest whole number.

Explanation:

Step1: Recall circumference formula

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

Step2: Substitute given diameter

Substitute $d = 71$ m into the formula: $C = \pi \times 71$

Step3: Calculate and round

Use $\pi \approx 3.1416$, so $C \approx 3.1416 \times 71 = 223.0536$. Round to the nearest whole number.

Answer:

223 m
