The diameter of the. To calculate the area of a sector of a circle we have to multiply the central angle by the radius squared and divide it by 2. The area of the segment of a circle is determined by subtracting the triangle formed inside the sector from the sector which has the segment.

Doing this will give you what fraction or percent of the entire circle the sector represents. Sector of a circle. The formula for sector area is simple - multiply the central angle by the radius squared and divide by 2.

In this triangle s is the side length of the polygon r is the radius of the polygon and the circle h is the height of the triangle. The polygon can be broken down into n isosceles triangles where n is the number of sides such as the one shown on the right. Area of a sector.

Note the circumference and area apply to the entire circle. Area of a sector of a circle θ r 2 2 where θ is measured in radians. Since the radius is a line segment from the center to the circle and the diameter d is a line segment from on side of a circle through the center of a circle and out to the other side of the circle it follows that a radius is 1 2 a diameter.
