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.
Whats angle is a 48?
48 is less than 90, so a 48 degree angle is an acute angle.
What is a 180 degree angle of a circle?
a straight line
What is the value of the degree of an angle in a semi-circle?
An angle subtended at the semicircular arc is 90 degrees.
What does 360 degree angle look like?
A circle because there are 360 degrees around a circle.
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.
Whats the compliment of a 100 degree angle?
The compliment of a 100 degree angle is a 80 degree angle.
Is a circle composed of degree?
Yes, a circle is in fact composed of a degree or angle.
Whats a acute angle?
an angle that is less than 90 degree's
What is the area of the shaded sector if the circle has a radius of 3 and the central angle is 90 degrees?
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
How do you find the area of a shaded region in a circle?
(pi * radius squared) * ( sector angle / 360 )
What is the area of the shaded sector if the circle has a radius of 7 and the central angle is 45 degrees?
19.23
What does a 331 degree angle look like?
A 331 degree angle is a reflex angle and it nearly looks like a circle because there are 360 degrees in a circle.
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.
