Answer:

  • center (1, 0)
  • radius 6

Step-by-step explanation:

Given

  (x -1)^2 +y^2 = 36

Find

  the circle's center and radius

Solution

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.
