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.
It depends on what the shaded and non-shaded parts look like!
Base X Height - pi(r)^2
(pi * radius squared) * ( sector angle / 360 )
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.

Find the area of the shaded region means find the area of the area that is shaded in or darkened.
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.

The probability is the ratio of the area of the shaded area to the area of the whole figure.
If we can't see the shaded area or if you don't tell us what it is, we'd just be guessing.

You either need to find the area of the triangle and subtract it from that of the rectangle OR you find the areas of the bits of the rectangle that are outside the triangle and add them together. Without more details of the triangle, it is not possible to give a more detailed answer.
Base X Height - pi(r)^2
(pi * radius squared) * ( sector angle / 360 )
Typically, when a mathematical problem wants you to find the value of a shaded area, it wants you to calculate the area. If the shaded area is a circle, the area can be found by multiplying pi by the square of the radius. If the shape is a triangle, the area is base times height, divided by 2. If the shape is a square or rectangle, the area is length times width.
