If one fifth of a region is not shaded then 4 fifths of the region is shaded. Fifths means there are five parts.
Neither. The region to the right of 5 should be shaded. (The shaded region being the solution region.)
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.

Find the area of the shaded region means find the area of the area that is shaded in or darkened.

The approximate area of the shaded region of 10 cm is 100 square centimeters.
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.

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.
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.
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.
