What is tertiary sector? Tertiary (Third) sectors: the activities of tertiary sector do not produce goods at its own, but assist in the process of production. For example: to sell the goods produced by primary and secondary sectors,trains and trucks are needed to transport them to the whole sale and retail markets, trains and trucks are needed ...
The length of the sector = (θ/360°)× 2πr. l = (40°/360°) × 2 × (22/7) × 7. l = 44/9 units. Example 2: Find the area of the sector of a circle if the radius of the circle is 20 units, and the length of the arc is 8 units. Solution: Given, radius = 20 units and length of an arc of a sector of circle = 8 units.

The formula for the perimeter of the sector of a circle is given below : Perimeter of sector = radius + radius + arc length. Perimeter of sector = 2 radius + arc length. Arc length is calculated using the relation : Arc length = l = (θ/360) × 2πr. Therefore, Perimeter of a Sector = 2 Radius + ((θ/360) × 2πr )
Solution. When the activities are based directly on the natural resources, it is known as primary sector. An example of primary sector is agriculture. Suggest Corrections. 107.
To form a cone, bring together both the radii of the sector and by using a adhesive tape, attach the ends and fix it on the hardboard. (see Fig. 28.5) Demonstration. Radius of the base of cone = r. Slant height of the cone = Radius of circle = l. Circumference of the base of cone = Arc length of sector = 2πr.
