Question

length of the sector is 48m and radius is 16m find ,area of the sector
​

Answer 1

Step-by-step explanation:

Here, length of arc, l=16 cm and r=9 cm

Length of arc, l=

360

o

θ

×2πr

16=

360

o

θ

×2π×9

∴θ=

2π×9

16×360

o

=

π

320

Now, area of sector, A =

360

o

θ

×πr

2

θ

∴A=

360

o

320/π

×π×9×9=72

Hence, the area of sectors is 72cm
