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?

Question

(1 point)
A. Negin should calculate the area of the circle
B. Negin should use the distance formula to calculate the length of segment AB
C. Negin should approximate the distance from A to B
D. Negin should calculate the circumference of the circle.

Answer 1

To prove that point B(7,4) lies on circle A, Negin's first step should be to:

B. Negin should use the distance formula to calculate the length of segment AB.

The distance formula will allow her to determine if the distance from the center of the circle (A) to point B is equal to the radius (3). If it is, then point B is on the circle.
