Answer:
Length is 13.2 cm , Area is 41.5 cm² and Perimeter is 25.8 cm
Step-by-step explanation:
Given:
Central angle of sector, = 120°
Diameter of the circle = 12.6 cm
⇒ radius of the circle, r = 6.3 cm
Value of π = 3.14
To find: Length of the arc of the sector, Area of the sector and perimeter of the sector.
Formula we use are as follows,
Perimeter of the sector = Length of arc + 2 × radius
So,
Perimeter of the sector = 13.2 + 2 × 6.3 = 25.8 cm
Therefore, Length is 13.2 cm , Area is 41.5 cm² and Perimeter is 25.8 cm
