WebGiven a circle with radius, r, centered at point (h, k), we can use the distance formula to find that: where (x, y) is any point on the circle. Squaring both sides of the equation, we get the equation of the circle: (x - h) 2 + (y - k) 2 = r 2. Notice that if the circle is centered at the origin, (0, 0), then both h and k in the equation above ... WebDec 7, 2016 · Here are the circle equations: Circle centered at the origin, (0, 0), x2 + y2 = r2 where r is the circle's radius. Circle centered at any point (h, k), ( x – h) 2 + ( y – k) 2 = r2 where ( h, k) is the center of the circle and r is its radius.

The point where tangent meets the circle is called point of tangency. The tangent is perpendicular to the radius of the circle, with which it intersects. Tangent can be considered for any curved shapes. Since tangent is a line, hence it also has its equation. create a burner emailWebThe standard form of the equation of the circle is given by, x-h 2 + y-k 2 = r 2. Where (h, k) is the center of the circle and r is the radius. Comparing the given equation with the standard form, we get: h = 3, k = 5 and r 2 = 25. Solve the equation r 2 = 25. r 2 = 25 r = ± 25 = ± 5.
