This form is also. Use this form to determine the center and radius of the circle. Center -2-2 radius of 6.
The radius is typically denoted as r or R.
The equation is x2y2-16x-14y770 As a circle is a point that moves so that its distance from a given point called center is always same called radius we should first calculate the distance of a point xy from the center at 87 and that should be 6 as radius is given to be 6. The variable represents the radius of the circle represents the x-offset from the origin. The radius is 5. 6 Write the equation of a circle with center.
