Step-by-step explanation:
Equation of line in slope point form is given as:
We have been given image of circle that passes through point . We are asked to find the radius of the circle.
First of all, we will find the center of the circle.
We can see that center of circle is at point .
Now we will use equation of circle to find radius.
, where, point (h,k) represents center of circle and r represents radius of circle.
Now we will substitute the coordinates of point and coordinates of center and solve for r as:
Switch sides:
Now we will take positive square root on both sides:
Therefore, radius of circle will be and center is at point .
Answer: C.
