Try designing a car without one!
Well, in math you solve the perimeter of circles and such, and learn understanding of them to help you with circles in real life.
circles are used to set bases of cylinders, diameters for barrels, tires, ect... if you CAN'T think of anything else a circle is used for, think HARDER and there is no real use for trapezoids accept in architecture and other design methods. :)
finding the measurement of a port hole on a ship
circles are used for the area of pools tables desk or any ferniture.they are also used for making products such as a cutout to look off of.
Proportions are used in real life to determine prices of things.
--actually they are used in real life. parabolas are seen in "parabolic microphones" or satellites. and there are others for both ellipses and hyperbolas.

Believe it or not, school is a real life situation. If you are using it in school it real life for you.
If you are in school and are studying trig then you are using trig in real life.
A pair of compasses are use to construct circles and arcs of circles
