Answer:
Circles are used for various applications in architecture, gardening, graphics, infrastructure, transportation, and more.
For example, arches are formed from part of a circle.
We also use circles to make spheres (such as ball bearings), cylinders (such as cans to preserve food and cups for drinking), and cones.
Circles are used in gardening to figure out how much space a plant needs around it to grow.
Circles are also used in engineering (such as in gears for automobiles).
Circles are used in graphics for rotation of objects on a computer screen (often a time parameter is used to keep an object spinning on the screen).
Circles are used to calculate the distance that a car has traveled (based on the circumference of the tires and how many times the axle has turned).
