Web29 de mar. de 2024 · To find the arc length with a sector area, multiply the sector area by 2. Then, divide the product by the radius squared ( (SA*2)/r^2). Your answer gives you the central angle in radians. You now have the central angle in radians, so simply multiply the central angle by the radius to find the arc length. Thanks! We're glad this was helpful. 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 …
