how to find percentage in a circle

To find the percentage of a circle that is shaded or occupied by something, you first need to determine the fraction of the circle that is shaded.

1. Measure the angle of the shaded area in degrees. Let's say the angle is 90 degrees.

2. Divide the angle by 360 (the total number of degrees in a circle) to find the fraction of the circle that is shaded. In this case, 90 degrees / 360 degrees = 1/4 or 0.25.

3. To convert the fraction to a percentage, multiply it by 100. In this case, 0.25 x 100 = 25%.

So, if a circle has a sector that is 90 degrees, it represents 25% of the total circle.
