HEY,,
HERE Is YOUR SOLUTION..
In a circle,,
radius (r) = 21cm
Area of sector = thetaπr^2/360
= 60/360 × 22/7 × 21 ×21
=11 × 21
= 231cm^2
-----------------------------------------------------
Area of sector = 1/2 r ×l
(l = length of arc )
231 = 1/2 × 21 × l
231 ×2 = 21 × l
462/21 = l
l = 22cm
___________HOPE IT HELPS YOU_______
_____-THANKS ______
