Circle A has a center at (0, 0) and a circumference of 5. Circle B has a center at (0, 0) and a radius of 1 unit. The rule (x, y) (kx, ky)is applied to circle A. What value of k would show that circle A is similar to circle B? Use the Equation Editor Tool to enter your answer.

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
