Step-by-step explanation:
Radius of the circle
Center of the circle (h, k) = (1.3, - 3.5)
Equation of the circle in center radius form is given as:
Plugging the values of h, k and r in the above equation, we find:
This is the required equation of the circle.

Answer:
<h2>
AC = 21</h2>
Step-by-step explanation:
Collinear points are points are points that lies on the same line. If point B is between A and C, then AC = AB+BC
Given AC = 21x, AB = 11 and BC = 11x-1, in order to find the value of x, we will substitute the given parameters in the relationship above to have;
![21x = 11+11x-1\\21x = 10+11x\\](https://tex.z-dn.net/?f=21x%20%3D%2011%2B11x-1%5C%5C21x%20%3D%2010%2B11x%5C%5C)
Subtracting 11x from both sides;
![21x-11x = 10+11x-11x\\10x = 10\\x = 1](https://tex.z-dn.net/?f=21x-11x%20%3D%2010%2B11x-11x%5C%5C10x%20%3D%2010%5C%5Cx%20%3D%201)
Since AC = 21x
substituting x = 1 into AC,
AC = 21(1)
AC = 21
