The area of a sector of a circle is the product of the ratio and the area of the circle. Area of sector AOB = EX: Find the area of a sector of a circle bounded by an arc of 600, if the circle has a diameter of 26. Segment of a Circle: The part of a circle bounded by an arc and the segment joining its endpoints is a segment of a circle.

The area of a circle is given by. Area = π × (radius) 2. A = π r 2. Example. Area = π r 2 = π × 52 = 3.14 × 25 = 78.5 cm2. Remember that area always has square units. In this case since the radius is in cm, the area is in square centimetres (cm2) In a parallelogram the opposite sides are parallel. Parallelogram area = b × h. A = b × h ...
