Your mission is to track incoming meteors to predict whether or not they will strike Earth. Since Earth has a circular cross section, you decide to set up a coordinate system with its origin at Earth's center. The equation of Earth's surface is \(\displaystyle{x}^{{2}}+{y}^{{2}}={40.68}\), where x and y are distances in thousands of kilometers.
