Q. What is the radius of the circle x2+y2=36x^2 + y^2 = 36?\newlineSimplify any fractions.\newline____
  1. Given equation: The given equation is x2+y2=36x^2 + y^2 = 36. This equation represents a circle centered at the origin (0,0)(0,0) with a radius rr. The general form of a circle's equation is (xh)2+(yk)2=r2(x - h)^2 + (y - k)^2 = r^2, where (h,k)(h,k) is the center of the circle and rr is the radius. By comparing the given equation with the general form, we can see that h=0h = 0, k=0k = 0, and r2=36r^2 = 36.
  2. Comparison with general form: To find the radius rr, we need to take the square root of r2r^2. The square root of 3636 is 66. Since the radius of a circle is always a positive value, we disregard the negative square root.\newliner=36=6r = \sqrt{36} = 6
