The answer will depend on what part of the circle is shaded.
Yes, that's sorta true. I think you are asking on how to find the area of a sector in a circle. If so, here's the formula: A= N/360 (πr^2)
or aka
Area of shaded area equal to the measurement of the central angle divided by 360 times pi to the second power.
:)
Just an EXAMPLE. A = 196/360 (π16^2)

To find the area of the shaded part in a rectangle, you first find the total area of the rectangle by multiplying its length by its width. Then, you subtract the area of the non-shaded part from the total area to get the area of the shaded part. The formula would be: Area of shaded part = Total area of rectangle - Area of non-shaded part
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
Area of a circle = pi*radius2
