Question

Find the area of sector of a circle of radius 3 cm if length of arc is 4 cm.

Answer 1

hope it will help you....

Answer 2

Answer:

Length of arc = Ø/360 × 2$\pi$r

=> Ø/180 × 22/7 × r = 4

=> Ø = 360 × 7/11 × 3

=> Ø = 840/11

Area of sector = Ø/360 × $\pi r^{2}$

=> 840/11 × 1/360 × 22/7 × 9

=> 6 sq cm
