Answer: The perimeter of the given sector is 5.5 cm.
Step-by-step explanation:
This can be solved as-
The radius of the circle= 9cm
The central angle of the given sector of the circle= 35°
The perimeter or circumference of a circle can be found by- 2×π × r, where r is the radius and the value of π is 3.14
The perimeter of a sector of the circle=
(Value of the angle)/ 360 ×2× π× r
= 35/360 × 2 × 3.14 × 9 = 5.5 cm
