Sector of the circle
WebSo to find the sector area, we need to find the fraction of the circle made by the central angle we know, then find the area of the total circle made by the radius we know. Then we just multiply them together. Let’s try an example where our central angle is 72° and our radius is 3 meters. First, let’s find the fraction of the circle’s ... WebThe 2 radii meet at the part of the circumference of a circle known as an arc, forming a sector of a circle. The formulas to calculate the sector of the circle are: Area of a sector …
