Area of a sector;
A=
(∅)/(360) \pi r^(2)
A=
(18)/(360) *3.14* 4^(2)
A=2.512 square units.

The area of the sector (As) of a circle may be calculated by the formula,
As = (a / 360) x π x r²
where a is the measure of angle in degrees and r is the radius. Substituting the known values,
As = (18 / 360) x 3.14 x (4²) = 2.512
Thus, the area of the sector is approximately 2.512 squared units.
