Sector of a Circle - Area, Perimeter and Arc Length Formula - BYJU
WebJan 30, 2024 · Formula for the Area of a Sector. The basic formula for the area of a circle, area \ (=\pi r^ {2}\) can be applied to find the area of sectors of the circle. The full circle has an angle of \ (2 \pi\) radians around the centre. So, the area of the sector with a central angle \ (\theta\) and having radius \ (r\) will be proportional to this ... Web2 Find the size of the angle creating the sector. Angle = 90° 90° (shown by the symbol of the right angle). 3 Substitute the value of the radius and the angle into the formula for the … WebTo calculate the area of a sector of a circle we have to multiply the central angle by the radius squared, and divide it by 2. Area of a sector of a circle = (θ × r 2 )/2 where θ is measured in radians. The formula can also be represented as Sector Area = (θ/360°) × πr 2, where θ is measured in degrees. ralfs bootshaus ruderclub rastatt
