Question

Please help me find this shaded reigon fast

Answer 1

Answer:

=293.7m²

Step-by-step explanation:

Area of the shaded region = area of the circle-area of the minor segment.

The area of the minor segment is calculated as follows.

Area= Area of sector - area of the triangle bound by the radii.

=∅/360πr²-1/2r²sin∅, where r is the radius of the circle and ∅ the obtuse angle bound by the radii.

=130/360×π×11.1²-1/2×11.1²sin130

=93.43m²

Area of the whole circle =πr²

=π×11.1²

=387.08m²

Area of the shaded region

=387.08m²-93.43m²

=293.65m²

≅293.7m² to the nearest tenth.
