WebNov 16, 2024 · r =√(x−h)2+(y −k)2 r = ( x − h) 2 + ( y − k) 2 Or, if we square both sides we get, (x−h)2+(y −k)2 = r2 ( x − h) 2 + ( y − k) 2 = r 2 This is the standard form of the equation of a circle with radius r r and center (h,k) ( h, k). Example 1 Write down the equation of a circle with radius 8 and center (−4,7) ( − 4, 7) . Show Solution WebApr 20, 2014 · 1) The equation of a circle is (x-h) 2 + (y-k) 2 = r 2 where (h,k) is the center of the circle and r is the radius. The center is (-2,3) and the radius is 8. Just plug those values into the equation. 3) The vertex-focus form of a parabola is 4p (y-k)= (x-h) 2 where p = the distance from the vertex to the focus and (h,k) is the vertex.
