We will determine the diameter by using the circumference formula, that is:
[tex]C=2\pi r[/tex]Now, we replace the values and solve for the radius (r):
[tex]75.36=2\pi r\Rightarrow r=\frac{75.36}{2\pi}\Rightarrow r\approx12[/tex]Now, since we know that the diameter of the circle is two times the radius then the diameter is approximately 24 m.
