Tutors, please sign in to answer this question.

I'm not sure what you're asking for; do you want us to give you examples of real-life applications of conic sections? Or do you want a real-life application that uses all four conic sections?

Ellipses - Planets/comets and other celestial bodies follow elliptical orbits.

Parabolas - satellite dishes and mirrors can be shaped as parabolas.

Hyperbolas - Lampshades cast hyperbolic shadows, and the cooling towers of nuclear reactors have a hyperbolic shape - lampshade: http://www.pleacher.com/mp/mgifs/gifs2/lamp.jpg and a cooling tower: http://www.pleacher.com/mp/mgifs/gifs2/hyp1.jpg

And I'm sure you can think of a few real life applications of circles!

## Comments

I want a word problem of a real life problem using a circle, but I've found one. Now I'm looking for ellipses and hyperbolas word problems and how they could be/are solved.
