(a)
To find: The center and radius of circle
(a)
Answer to Problem 18T
The center of circle is
Explanation of Solution
Section1:
The given equation of circle is
The equation of circle with center
Rewrite the given equation,
Compare above equation with equation (1) to get the center
Thus, the center of circle is
Section2:
From the section1 the center of circle is pass through origin and the radius of circle is 5 that is shown below,
