A circle has a circumference of 400 units. What is the approximate diameter of the circle?

To find the diameter of a circle given its circumference, we can use the formula: \[ \text{Circumference} = \pi \times \text{Diameter} \] Given that the circumference of the circle is 400 units, we can set up the equation: \[ 400 = \pi \times \text{Diameter} \] To find the diameter, we can rearrange the equation to solve for the diameter: \[ \text{Diameter} = \frac{400}{\pi} \] Now, we can calculate the approximate value of the diameter using the value of \( \pi \) as approximately 3.14159. Calculate the value by following steps: - step0: Calculate: \(\frac{400}{\pi }\) The approximate diameter of the circle is 127.32 units.
