Question 1179503: An airport is located at D(0,0). A plane is currently positioned at C(-9, - 16). The radar system at the airport covers the area defined by x2 + y2 = 324. Will the plane show up on the radar at its current position? Explain.

x^2+y^2=324 is a circle with center at D(0,0) and radius sqrt(324)=18.

The distance of the plane from the airport is sqrt%289%5E2%2B16%5E2%29.

Calculate that distance and see whether the plane's distance from the airport is more or less than 18; then answer the question with an appropriate explanation.
