Step-by-step explanation:
Answer:
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
We have the slope 
and the point 
.
Substitute:
- point-slope form
Convert to the slope-intercept form (y = mx + b):
<em> use the distributive property</em>
<em>add 4 to both sides</em>
- slope-intercept form
Given that we need to determine the radius of the circle.
<u>Radius:</u>
By definition of radius of circle, the radius is the length of the line which is drawn from the center of the circle to any point on the circle.
From the figure, we need to determine the radius of the circle.
As, we can see that, the distance from the center of the circle to the point on the circle is 11 cm.
Since, we know that, the radius is the distance from the center of the circle to the point on the circle then, the radius of the given circle is 11 cm
Thus, radius of the circle is 11 cm.
