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
The radius
A circle is defined as the set of all points in a plane that are equidistant from a fixed point known as the center. The distance from the center to any point on the circle is called the radius. Mathematically, a circle can be represented by the equation ( (x - h)^2 + (y - k)^2 = r^2 ), where ( (h, k) ) are the coordinates of the center and ( r ) is the radius.
The radius of a unit circle is 1. A unit circle is defined as a circle with a center at the origin (0, 0) and a radius of one unit. This means that all points on the circle are exactly one unit away from the center.

this is impossible
Without an equality sign it can't be considered to be an equation but in general the equation of a circle whose centre is at (a, b) and radius is r is:- (x-a)^2+(y-b)^2 = r^2
The equation of the circle is: x^2 + y^2 = 81
