Perimeter of major sector
WebWhat is a sector of a circle? A sector of a circle is formed when a circle is divided using two radii.. Each sector has an angle between the two radii.The sector with an angle less than 180 degrees is called a minor sector and the sector with an angle greater than 180 degrees is … WebExample 1: Find the perimeter and area of the sector of a circle of radius 6 cm and length of the arc of the sector as 22 cm. Perimeter of the sector = 2r + length of the arc = (2 × 6 + 22) cm = 34 cm For area, first find the central angle θ. πrθ/180° = 22 θ = 210° So, area of the …
