If you mean: (x-2)^2 +(y+4)^2 = 6
Then its center is at (2,-4) and its radius is the square root of 6
2*pi*radius of the circle or diameter*pi where pi = 3.1416 or 22/7 and is usually rounded to 3.14.
22 ft. The diameter is the measurement of a circle through the center from side to side and is equal to two times the radius.

Radius of the circle is sqrt*[(5-2)2 + (6-2)2] = 5 So the equation is (x - 5)2 + (y - 6)2 = 25

(x-9)2 + y2 = 484The center is atx = 9y = 0The radius of the circle is 22 .
Pi is 22/7. Therefore, the equation for finding the circumference of a circle using fractions is: 22/7 mutiplied by the diameter of the circle :)

A circle with centre (xo, yo) and radius r has formula: (x - xo)2 + (y - yo)2 = r2 For circle with centre (1, 5) and radius 2 this is: (x - 1)2 + (y - 5)2 = 22 x2 - 2x + 1 +y2 - 10y + 25 = 4 x2 - 2x + y2 - 10y + 22 = 0
Radius of the circle is sqrt*[(5-2)2 + (6-2)2] = 5 So the equation is (x - 5)2 + (y - 6)2 = 25

We have: x^2 + y^2 + 10x + 2y + 22 = 0 We want to find the standard equation for a circle, which is: (x - a)^2 + (y - b)^2 = r^2 Where (a,b) is the center of the circle, and the radius is r. Regroup with like variables, and move the constant term to the right: x^2 + 10x + y^2 + 2y = -22 complete the square on both quadratics on the left: x^2 + 10x + c + y^2 + 2y + d = -22 + c + d find c, such that 2 * (c^(1/2)) = 10 and find d, such that 2 * (d^(1/2)) = 2 c = 25 d = 1 x^2 + 10x + 25 + y^2 + 2y + 1 = -22 + 25 + 1 (x + 5)^2 + (y + 1)^2 = 4 We now have the standard equation for a circle, which gives us a center at: (-5, -1) and which has a radius of 2.
