2102.13 mm^2

Attached is a completed image of the question

Step-by-step explanation:

Given;

Radius of the circle r = KL = 27.1 mm

Angle of unshaded region = 32°

The total angle in a circle is 360°

Angle of shaded region θ = 360° - angle of unshaded region.

θ = 360° - 32° = 328°

The Area of a circle = πr^2

Area of shaded region A = (θ/360)πr^2

Substituting the given values;

A = (328/360)×π × 27.1^2

Area of shaded region A = 2102.13 mm^2
