### How do you find the Area of a shaded region?

This question is too vague to have an answer, but here is one.For the shaded area (pie wedge) of a circle, find the area of the circle and multiply by the ratio of the wedge angle to the entire circle (angle/360).For the shaded region of a triangle, find the area of the smaller triangle, if necessary using trig functions to define a known angle or length of a side.For other polygons, you may be able to divide the area into triangles separately, then sum their areas.

### What is the area of the shaded sector if the circle has a radius of 8 and the central angle is 100 degrees?

Assuming the shaded sector has the angle of 100o (without seeing the diagram, it could be the other sector, ie the one with an angle of 260o): The sector is 1000 &divide; 360o = 5/18 of the circle. Thus its area is 5/18 that of the circle: area = 5/18 x &pi; x 82 ~= 55.9 units2
