12f=m
It can also be m/12=f, but since it is asking for inches to feet the first one is better

The picture in the attached figure
we know that
area of a sector=(∅*pi/360°)*r²--------> when ∅ is in degree
in this problem
∅=120°
r=4 units
so
area of a sector=(120°*pi/360°)*4²-------> (120°/360°)*(16*pi) units²
The <span>
expressions to find the area of the shaded sector is</span>
(120°/360°)*(16*pi) units²(1/3)*(16*pi)----> (16/3)*pi units²
the area of the shaded sector is (16/3)*pi units²
