Question

find the area of sector whose
length of the arc is 12.5 cm and radius is 6 CM ​

Answer 1

Answer:

perimeter of the sector=12.5+2(6)=24.5

let angle subtend by the arc be =@

Step-by-step explanation:

=@/360×2πr=24.5

=@/360×37.68=24.5

=@/360=24.5/37.68

=@/360=0.65

area of the sector=@/360×πr^2

so,πr^2=113.04

=@/360×πr^2=0.65×113.04

=73.476
