Answer:
Circles are special ellipses that have a single constant radius around a center. Circles and their various properties, such as the radius, diameter, circumference and area, have applications in real life. If the radius of the circle is known, all the other parameters can be calculated. Important information can be determined for real life applications based on the parameters. For example, knowing the circumference of the planets helps us compare their relative sizes, and artificial satellites that are launched travel in orbits of certain circumference.

Answer:
Circles are still evident in transportation where they appear in vehicle tires, roundabouts in roads, engine crankshafts, and road designs. GPS also relies on circles when determining distance. It identifies points and calculates the distance between the satellite and the point using a circle theory.
