WebThe circumference of a circle is C = 2πr. If we divide both sides of this equation by r, we create the ratio of the circumference to the radius, which is always 2π regardless of the length of the radius. So the circumference of any circle is 2π ≈ … 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! ( 9 votes) Flag hills science diet causing diarrhea https://shoptauri.com
