Question

the center of the circle on the line y=2x and line x=1 is tangent to the circle at (1,6). how long is the radius of the circle

Answer 1

Answer:

4

Step-by-step explanation:

Center of the circle: (1, 2)

Tangent of the circle: (1, 6)

Radius:

x2 - x1 = 1 - 1 = 0

y2 - y1 = 6 - 2 = 4

(0, 4). Radius is 4.
