The approximate length of the diameter,d of the circle is 250 ft
<h3>How to find the diameter of a circle</h3>
Circumference of the circle = 250π
- Circumference of a circle = 2πr
250π = 2πr
250π / 2π = r
125 = r
Recall,
Radius, r of a circle = Diameter, d ÷ 2
125 = d/2
d = 125 × 2
d = 250
Therefore, the diameter of the circle is 250 ft
