The area inside a full circle is given by the formula: Area = Pi x r x r where r is the length of the circle's radius.
However, the angle of 90 degrees is only one quarter of a rotation of a line about a point at its end, so the required area is one quarter of the full area.
So the required area is (Pi x r x r) divided by 4
A fairly accurate answer is found if we use the value 3.14 for Pi
It is interesting that the number Pi cannot be written down exactly as a fraction or a decimal. It is called an "irrational" number.

How to find area of a shaded area of a shaded region in a circle?
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
What is the approximate area of the shaded sector in the circle below 18cm?
To find the area of a shaded sector in a circle, you need the radius and the angle of the sector. Assuming the radius of the circle is 18 cm, the area of the entire circle is given by the formula (A = \pi r^2), which equals approximately (1017.88 , \text{cm}^2). If you know the angle of the sector in degrees, you can calculate the area of the sector using the formula (A_{sector} = \frac{\theta}{360} \times A_{circle}), where (\theta) is the angle of the sector. Without the angle, I cannot provide the exact area of the shaded sector.
What is the approximate area of the shaded area of the shaded sector 180 degrees?
To find the area of a shaded sector with a 180-degree angle, you can use the formula for the area of a sector: ( \text{Area} = \frac{\theta}{360} \times \pi r^2 ), where ( \theta ) is the angle in degrees and ( r ) is the radius. For a 180-degree sector, the formula simplifies to ( \text{Area} = \frac{1}{2} \pi r^2 ). Thus, the area of the shaded sector is half the area of the full circle with radius ( r ).

How do you find the Area of a 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.
