Answer:
The radius is approximately 1249 units.
Explanation:
Hello!
The formula for the circumference of a circle of radius r is C = 2πr. We want to find r when the circumference is 7850 units. To do this, solve C = 2πr for r first:
Dividing both sides of the above equation by 2π, we get:
7850 units
------------------ = approximately 1249 units.
2π
The radius is approximately 1249 units.
