There are two formulas that you need to consider
the first is of arc length represented by 'S' wch is equals to
S=r@
where s is the arc length r is th radius and @ is theta.
The second is Area of sector = 0.5 (r^2)(@)
(i)find the length of Ax
data=
r= 12cm
@= ᅲ/6
tan = opp/adj
tan x= Ax/ 12
Tan ᅲ/6 = Ax/12
Ax= 12 x root3 / 3
Ax= 4 root 3 cpouldnt find a suitable application
