To find the approximate length of the diameter, we need to use the formula for the circumference of a circle, which is C = πd, where C represents the circumference and d represents the diameter.
In this case, we are given that the circumference of Circle O is approximately 250π ft. We can set up the equation as follows:
250π = πd
To solve for d, we can divide both sides of the equation by π:
250π / π = πd / π
Simplifying the equation, we get:
250 = d
Therefore, the approximate length of the diameter, d, is 250 ft.
In the given answer choices, the option that matches the approximate length of the diameter, d, is:
d. 250 ft
