Point p (1, 7) is located on circle c. the center of circle c is (-2, 3). what is the radius of the circle?

Radius = 5 units

Step-by-step explanation:

We can use the formula of getting magnitude of a line joining two points;

(x1, y1) and (x2, y2)

Length = √((x2-x1)² + (y2-y1)²)

Therefore;

In this case the radius will be; PC

Length of PC = √((3-7)² + (-2-1)²)

                      = √((-4)² + (-3)²)

                      = √(16 +9)

                      = √ 25

                      = 5 units

Thus the radius is 5 units
