perimeter of sector

Print The area of a circle is and the perimeter or circumference is A sector is a fraction of a circle. To find the area of a sector, we just find that fraction of the area of a circle. The sector to the right is a fraction of the circle to the left so the the area of the sector is

If you take a part of the circumference of a circle then the distance along this arc is called the arc length. So since the arc length is part of the circumference of a circle, then the arc length of the sector can be found by using the following formula: l = (x/360) × π × d

A sector (of a circle) is made by drawing two lines from the centre of the circle to the circumference, and it looks like the usual ‘wedge’ cut from a cake. There are two special cases. If the angle is 180 degrees then the sector is a semi-circle. If the angle is 360

A circular sector or circle sector (symbol: ⌔), is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector. In the diagram, θ is the central angle in radians, r {\displaystyle r} the radius of the circle, and L {\displaystyle L} is the arc length of
