Circle Circumference Formula: The formula for the circumference of a circle is $C = \pi d$ , where $C$ is the circumference and $d$ is the diameter.
Substitute Values: We know the circumference is $11,304$ units and we're using $3.14$ for $\pi$ . So, we have $11,304 = 3.14d$ .
Calculate Diameter: To find the diameter, we divide the circumference by $\pi$ : $d = \frac{11,304}{3.14}$ .
Final Diameter Calculation: Calculating the diameter: $d = \frac{11,304}{3.14} = 3600$ units.
