Question 35

Pizza Planet delivers pizza within a 15 mile radius of their store. If this area is represented graphically, with Pizza Planet located at (2, 4), what is the equation that represents the delivery area?

(x + 2)² + (y + 4)² = 15

(x - 4)² + (y - 2)² = 115

(x - 2)² + (y - 4)² = 225

(x + 4)² + (y + 2)² = 15
