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 shaded part in a rectangle, you first find the total area of the rectangle by multiplying its length by its width. Then, you subtract the area of the non-shaded part from the total area to get the area of the shaded part. The formula would be: Area of shaded part = Total area of rectangle - Area of non-shaded part
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
find the area of the shaded sector 12cm and 24°
Either directly or by finding the area of the whole and subtracting the area of the non-shaded part.
To find the area of a shaded region, you first need to identify the shapes involved. Calculate the area of each individual shape separately using the appropriate formulas (e.g., area of a rectangle = length x width, area of a circle = πr^2). Then, subtract the area of any non-shaded regions from the total area to find the area of the shaded region. Be sure to pay attention to any overlapping areas or irregular shapes that may require more complex calculations.
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.
Well, darling, if you shaded all but three eighths of the rectangle, then the shaded area is 5/8 of the total rectangle. To find the percentage of the rectangle that is not shaded, you subtract the shaded area from 100%. So, 100% - 62.5% (5/8 as a percentage) = 37.5%. Voilà, 37.5% of the rectangle is not shaded.
You use proportions
The probability is the ratio of the area of the shaded area to the area of the whole figure.
it is actually very easy what you do is find the area of both shapes then if your problem is like find the chances of hitting the shaded area you do area of shaded divided by the total area of the whole object then multiply that by 100
If we can't see the shaded area or if you don't tell us what it is, we'd just be guessing.
There is no shaded space (indeed, no triangle) so the answer must be 0.
