What is a ‘sector’?
A sector of a circle is essentially a proportion of the circle that is enclosed by two radii and an arc.
Sector area formula
The equation for calculating the area of a sector is as follows:
area = πr2 * (A / 360)
where r is the radius of the circle and A is the angle of the arc in degrees.
