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

Well the formula you showed me on the last question we had to square the radius and 15^2 = 225. Right?

nnesha · Answer

lol yes right 
and you're lucky there is only one 225
