x^2 + y^2 = 81
x2 + y2 = 81
The equation of a circle is given by the formula ((x - h)^2 + (y - k)^2 = r^2), where ((h, k)) is the center and (r) is the radius. For a circle with a center at ((0, 2)) and a radius of 11, the equation becomes ((x - 0)^2 + (y - 2)^2 = 11^2). Simplifying this, the equation is (x^2 + (y - 2)^2 = 121).
x2+(y - 2)= 121
(x-0)² + (y-0)² = r²
To find the standard equation for a circle centered at the origin, we use the distance formula to define the radius. The equation is derived from the relationship that the distance from any point ((x, y)) on the circle to the center ((0, 0)) is equal to the radius (r). Thus, the standard equation of the circle is given by (x^2 + y^2 = r^2). Here, (r) is the radius of the circle.
The equation of the circle is: x^2 + y^2 = 81
x2 + y2 = 81
The equation of a circle is given by the formula ((x - h)^2 + (y - k)^2 = r^2), where ((h, k)) is the center and (r) is the radius. For a circle with a center at ((0, 2)) and a radius of 11, the equation becomes ((x - 0)^2 + (y - 2)^2 = 11^2). Simplifying this, the equation is (x^2 + (y - 2)^2 = 121).
x2+(y - 2)= 121
(x-0)² + (y-0)² = r²
(x - 0)2 + (y - 0)2 = 49
The equation is: (x -0)^2 +(y -2)^2 = 121
(x-3)2+y2=144
The general equation of a circle is given by the formula(x - h)2 + (x - k)2 = r2, where (h, k) is the center of the circle, and r its radius.Since the center of the circle is (0, 0), the equation reduces tox2 + y2 = r2So that the equation of our circle is x2 + y2 = 36.
x2+y2+4x+2y+3=0(x+2)2 + (Y+2.5)2 = 3This is the equation of circle with center at (-2,-2.5) with radius 3.5
To find the standard equation for a circle centered at the origin, we use the distance formula to define the radius. The equation is derived from the relationship that the distance from any point ((x, y)) on the circle to the center ((0, 0)) is equal to the radius (r). Thus, the standard equation of the circle is given by (x^2 + y^2 = r^2). Here, (r) is the radius of the circle.
center (3,0) radius 12 So the equation is (x-3)^2 + y^2 = 144 → y^2 + x^2 - 6x - 135 = 0 in general a circle of radius r centered at (h, k) has the equation: (x - h)^2 + (y - k)^2 = r^2
