The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.

The area of the shaded region is 1265.42 meters squared, since I subtracted the two totals of both the unshaded region and the shaded region of a circle.
You divide the area of the shaded region by the area of the full circle. For example, if the radius of the shaded region is 2 meters, the probability would be 4pi / 36pi, or 1/9. If the shaded region is a 'slice' of the circle, the chance is just the fraction of the circle which the 'slice' is.
If one fifth of a region is not shaded then 4 fifths of the region is shaded. Fifths means there are five parts.
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.
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.
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 approximate area of the shaded region of 10 cm is 100 square centimeters.
The area of the shaded region is 1265.42 meters squared, since I subtracted the two totals of both the unshaded region and the shaded region of a circle.
Simply put, the area of a shaded region can be calculated using: Area of shaded region = Total area - Area of unshaded region. Sometimes finding the area is simple, and other times, not so easy. Often , it is necessary to subdivide areas into shapes mathematics provides regular area formulas for.
(pi * radius squared) * ( sector angle / 360 )
This question needs additional information, To get the area of the shaded area get the difference between the total area and the un-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.
