The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.

That will depend on the length or angle of the arc which has not been given

It is: 110/360*pi*12*12 = 44*pi square units

It depends whether the UNSHOWN figure has the shaded sector as the sector which includes the 90° angle, or the one which excludes it. Assuming that it is the sector including the 90° angle, ie the question should have been written: What is the area of a sector of a circle with a radius of 3 units when the angle of the sector is 90°? It is a fraction of the whole area of the circle. The fraction is 90°/360° (as there are 360° in a full turn and only 90° are required) = 1/4 Area circle = π × radius² = π × (3 units)² = 9π square units → area 90° sector = ¼ × area circle = ¼ × 9π square units = 9π/4 square units ≈ 7.1 square units

Area of sector = 60/360ths ie 1/6th of the total area; Total area = 12 x 12 x 3.14 = 452.16 cm2 Area of sector = 452.16/6 = 75.36 cm2
