WebNov 1, 2024 · Area of sector = ½ r 2 θ= ½ x 9 2 x (5π/3) = 67.5 π sq. cm. Ans: length of the arc is 15π cm and the area of the sector is 67.5π sq. cm. Example – 05: The perimeter of a sector of a circle of area 25π sq. cm is 20 cm. Find the area of the sector. Given: Area of circle = 25π sq. cm, Perimeter = 20 cm WebThe sector area is recalculated as you drag. What the formulae are doing is taking the area of the whole circle, and then taking a fraction of that depending on what fraction of the circle the sector fills. So for example, if the central angle was 90°, then the sector would have an area equal to one quarter of the whole circle.

WebFirst we need to convert angle given in degrees to radians: θrad = Angle In Degrees ∗ π 180. θrad = 45^o ∗ 3.14 180. θrad = 141.3 180. θrad = 0.785rad. Now using the area of a sector of a circle formula: Area Of Sector = α ∗ r2 2. Putting the value given in the statement: Area Of Sector = 0.785 ∗ (3)2 2. WebA sector is the area of a circle which has been enclosed by two radii and the arc between them. A sector is not to be confused with a segment of a circle. A segment is when the area enclosed by the chord of a circle and the arc of the chord. Report an Error Example Question #2 : Area Of A Sector
