Question

What is the length of the arc of the sector, whose radius is 15cm and intended angle is 30°​

Answer 1

Answer:

Area of sector of circle =30 cm

2

radius of circle =15 cm

Area of sector =

360

θ

×πr

2

360

θ

=

πr

A

=

π×15×15

30

=

15π

2

now length of arc =2πr=

360

θ

=2π×15×

15

2

Length of arc =4 cm
