The radius of front wheel is 21 cm. the arc lenght of the training wheel which is subtended by angle 60° is 6.25 cm. the front wheel of the bike makes 40 complete rotations. find the number of complete rotations made by the training wheel.

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
