Circles and their equations
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 … WebExpert Answer. (A) Centred at ( -2 , 3 ) and radius of 5 units Equation = ( x + 2)2 + ( y - 3 )2 = 25 == x2 + y2 + 4x - 6y - 12 = 0 (B) Diametr = 1/2 === radius = 1/4 = 0.25 …. View the …
