How Do You Find The Area Of A Shaded Region Of A Circle?

Your question is ambiguous as it does not give details of the size of the circle or the size of the shared area. I am afraid that I will not be able to answer this problem for you exactly, but there are some helpful sums that may help you in calculating the shaded region of your circle.

• Some terminology that may help

In order to find the sum of the circle or a shaded area within a circle there may be some terms that you need to know. The diameter of the circle is the length of a line drawn between two points of a circle running through the centre point (cutting the circle in half). The radius of a circle is a line from the centre point of the circle that extends in any direction to a point at the circle's boundary. The radius is exactly half the length of the diameter. The circumference of a circle is the length of the boundary line and is calculated using c=2πr. The circumference of a circle is calculated using the constant π (pi) due to the curve of the circle.

• The shaded region

I am assuming that the shaded region is within the circle itself, making up a part of the circle. By calculating the radius, diameter and circumference of the circle you will be able to calculate the shaded area. For example, the equation A=πr^2 gives you the area of the circle. Now you will just have to work out what proportion of the circle is taken up with your shape, thereby being able to find the area of the shaded region of the circle.

Firstly, we must to know the formula of area.
