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.
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
You will need to divide the shaded area into smaller parts, such as triangles or rectangles, or find the length of sides of these polygons.
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
Base X Height - pi(r)^2
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
Well, honey, the area of a shaded region is simply the difference between the total area and the area of the unshaded parts. Just calculate the area of the entire shape and subtract the areas of any parts that aren't shaded. It's basic math, darling, nothing to lose sleep over.

To find the area of the circle pi*radius*squared and subtract the area of the figure inside
You find the area of the whole square first. Then you find the area of the circle inside of it And then subtract the area of the circle from the area of the square and then you get the shaded area of the square
You will need to divide the shaded area into smaller parts, such as triangles or rectangles, or find the length of sides of these polygons.
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
If we can't see the shaded area or if you don't tell us what it is, we'd just be guessing.
The probability is the ratio of the area of the shaded area to the area of the whole figure.
The area is 40/360*pi*r^2 = 28.16 square cm.
