What is the radius of a circle with the following equation...10 points

(x - 2)^2 + (y - 9)^2 = 36

The standard form of a circle is (x - a)^2 + (y - b)^2 = r^2 where the center is (a,b) and the radius is r .

Looking at the above equation:

r^2 = 36
so the radius r = sqrt(36) = 6

Radius = √36 = 6 units
