The added complexity comes from the need to calculate how much of a circle a sector accounts for. By substituting the above given data in the previous function; (i.e.) These units are related as follows: 10 mm = 1 cm 100 cm = 1 m 1000 m = 1 km The word 'perimeter' is also sometimes used instead of circumference. The area of the sector is . : 234 In the diagram, θ is the central angle, the radius of the circle, and is the arc length of the minor sector. so the formula for finding perimeter of angle 60 degree = length of arc +2*radius so the perimeter will be =(x/360°) 2 πr + 2r By putting the values we will got = (60 ° /360 °)( 2 *3.14 * 10.5) + 2* 10.5 So upon solving the perimeter of sector will be = 32 cm. Perimeter … The perimeter of a sector a circle of radius 5.7 m is 27.2 m. Find the area of the sector. A circle containing a sector can be further divided into two regions known as a Major Sector and a Minor Sector.
