Answer:
- center (1, 0)
- radius 6
Step-by-step explanation:
<u>Given</u>
(x -1)^2 +y^2 = 36
<u>Find</u>
the circle's center and radius
<u>Solution</u>
Compare the given equation to the standard form equation for a circle.
(x -h)^2 +(y -k)^2 = r^2 . . . . . . centered at (h, k) with radius r
This tells you ...
- h = 1
- k = 0
- r = √36 = 6
Your circle is centered at (1, 0) and has a radius of 6.
