How To Find Area Of A Circle EquationThe 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. To determine the circumference of a circle from its area follow these steps Multiply the area by Take the square root of the result from Step 1 Multiply by 2 You found the circle s circumference from its area Well done
