The center of circle A is at (4,4), with a radius of 3. What should Negin’s first step be to prove that the point B(7,4) lies on the circle? (1 point) Responses Negin should use the distance formula to calculate the length of segment AB. Negin should use the distance formula to calculate the length of segment upper A upper B . Negin should approximate the distance from A to B. Negin should approximate the distance from upper A to upper B . Negin should calculate the circumference of the circle. Negin should calculate the circumference of the circle. Negin should calculate the area of the circle.

Answer 1

Negin’s first step to prove that the point B(7,4) lies on the circle should be to use the distance formula to calculate the length of segment AB.

Specifically, she should calculate the distance between the center of the circle A(4,4) and the point B(7,4), and then compare that distance to the radius of the circle (which is 3). If the distance equals the radius, then point B lies on the circle.
