Its (x-2)to the second power +(y-v) to the second power=r2
That's the equation of a circle with its center at the origin and a radius of 8.
No, the distance around a circle is called the circumference. The radius is the distance from the exact center of the circle to the edge of the circle and is one half of the diameter. The diameter is one straight line passing through the center of the circle from one end to the other. The circumference can be determined from the following equation: C = pi * d or C = 2*pi*r
The equation of a circle can be written in the form (x-h)2 + (y - k)2 = r2, where r is the radius, and (h,k) is the center. So for your example, the equation would be: (x- 5)2 + (y - 3)2 = 72
If you mean: (x+9)^2 + (y+5)^2 = 64 Then the center of the circle is at (-9,-5) and the radius is 8
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
Equation of any circle, with any radius, and its center at any point: [ x - (x-coordinate of the center) ]2 + [ y - (y-coordinate of the center) ]2 = (radius of the circle)2
The standard equation of a circle, with center in (a,b) and radius r, is: (x-a)2 + (y-b)2 = r2
depends on the equation.
The equation of circle is (x−h)^2+(y−k)^2 = r^2, where h,k is the center of circle and r is the radius of circle. so, according to question center is origin and radius is 10, therefore, equation of circle is x^2 + y^2 = 100
Center of circle: (6, 8) Radius of circle: 3

this is impossible
The equation of the circle is: x^2 + y^2 = 81
Centre of the circle: (3, 8) Radius of the circle: 2 Cartesian equation of the circle: (x-3)^2 + (y-8)^2 = 4
x2 + y2 = 64
x² + y² = 4.
x² + y² = 81.
