(h,k) = ( , ) The center of the circle is at the origin. A point on the circle is at (3,4). The radius = (x - )2 + (y - )2 = (h,k) = ( , ) The radius = The center of the circle is at the origin.A point on the circle is at (-6,8). The equation of the circle is: (x- )2 + (y- )2 = The radius = The center of the circle is at the (4,5)A point on the circle is at (-2,-3). (h,k) = ( , ) The radius = The equation of the circle is: (x )2 + (y )2 = The center of the circle is at the (-7, 4)A point on the circle is at (-2,16). MUST type in + or - Diameter = The radius = The equation of the circle is: (x )2 + (y )2 = The center of the circle is at the (4,1)A point on the circle is at (1,5). MUST type in + or - Diameter = The equation of the circle is: (x )2 + (y )2 = The center of the circle is at the (6,-4)A point on the circle is at (2,3). The radius = MUST type in + or - The endpoints of the diameter of a circle are at (-6,0) and (6,0). center point (h,k) "midpoint" = ( , ) The radius = Equation of Circle (x - )2 + (y- )2 = The diameter = The endpoints of the diameter of a circle are at(-3,2) and (5,6). The radius = The radius = center point (h,k) "midpoint" = ( , ) (x )2 + (y )2 = Equation of Circle tenths exact |
