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.
That depends on what area you choose to shade.
What do you call shaded part?

You cannot have a shaded area of 4 cm since area cannot be measured in centimetres.
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
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.
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.
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 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.
If 5.7 of a region is shaded, then 94.3% of the region is not shaded. This can be calculated by subtracting the shaded percentage from 100%.
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.
96.86 hehe ;)
The answer depends on which area is shaded for each inequality. I always teach pupils to shade the unwanted or non-feasible region. That way the solution is in the unshaded area. This is much easier to identify than do distinguish between a region which is shaded three times and another which is shaded four times.
