WebFeb 2, 2024 · There are three circle radius formulas, depending on what number you know: The radius of a circle from the area: if you know the area A, the radius is r = √ (A / π). The radius of a circle from … WebThe standard equation for a circle centred at (h,k) with radius r is (x-h)^2 + (y-k)^2 = r^2 So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2 Next, substitute the values of the given point (2 for x and 11 for y), getting 3^2 + 18^2 = r^2, so r^2 = 333. The final equation is (x+1)^2 + (y+7)^2 = 333 Hope this helps!
