Question

What's the perimeter of a sector with radius 10.5 cm and sector angle 60 degree?

Answer 1

Answer:

32 cm

Step-by-step explanation:

Given :- Radius = 10.5 cm and Sector angle = 60°

Perimeter of a sector of a circle = [(theta/360°)*2πr] + (2r)

⇒[(60/360)*2*22/7*10.5] + (2*10.5)

⇒ 1*462/6*7 + 21

⇒ 462/42 + 21

⇒ 11 + 21

⇒ 32 cm

So, the perimeter of sector is 32 cm
