Given data:
The given diameter is D=100 m.
The expression for the circumference of the circle is,
[tex]C=\pi D[/tex]Substitute the given value in the above expression.
[tex]\begin{gathered} C=\pi(100\text{ m)} \\ =314.16\text{ m} \end{gathered}[/tex]Thus, the circumference of the circle is 314.16 m.
