Final answer:
The radius of the circle is 100 feet.
Step-by-step explanation:
To find the radius of the circle, we need to use the formula for the circumference of a circle, which is C = 2πr. We are given that the circumference is 200π feet, so we can set up the equation as 200π = 2πr. To solve for r, we can divide both sides of the equation by 2π, giving us r = 100 feet.
