Question

Springfield middle school built a track in the shape of a circle. The diameter of the track is 100 meters. What is the circumference of the track

Answer 1

Given data:

The given diameter is D=100 m.

The expression for the circumference of the circle is,

$C=\pi D$

Substitute the given value in the above expression.

$\begin{gathered} C=\pi(100\text{ m)} \\ =314.16\text{ m} \end{gathered}$

Thus, the circumference of the circle is 314.16 m.
