Question

Find the area of a segment (interm of π )of a circle with center angle 30° and radius of 8 cm​

Answer 1

⇒ θ=30

o

and r=4cm

⇒ Length of an arc =

360

o

θ

(2πr)

Where, θ is angle subtended at a center.

2πr is circumference of a circle.

⇒ Length of an arc =

360

o

30

o

×2π×4

⇒ Length of an arc =

12

2π×4

∴ Length of an arc =

3

2π

instead of 8 I write 4 so you can solve from himself

I hope this helps you
