Area of a Sector of Circle
Area of a sector of a circle is the space occupied inside a sector of a circle’s border. A semi-circle is likewise a sector of a circle, where a circle has two equal-sized sectors.
Area of a sector of a circle formula is given below:
A = (θ/360°) × πr2
where,
θ is the sector angle subtended by the arcs at the center (in degrees),
r is the radius of the circle.
Area of Quadrant of circle
A quadrant of a circle is the fourth part of a circle. It is the sector of a circle with an angle of 90°. So its area is given by the above formula
A = (θ/360°) × πr2
Area of Quadrant = (90°/360°) × πr2
= πr2 / 4
Area of a Circle: Formula, Derivation, Examples
Area of a Circle is the measure of the two-dimensional space enclosed by a circle. It is mostly calculated by the size of the circle’s radius.
Let’s learn how to find the area of the circle using the formulas, with the help of examples.
