WebSep 15, 2024 · Solution: As with arc length, we have to make sure that the angle is measured in radians or else the answer will be way off. So converting θ = 117 ∘ to radians and using r = 3.5 in Equation 4.3.1 for the area A of the sector, we get. θ = 117 ∘ = π 180 ⋅ 117 = 2.042 rad ⇒ A = 1 2 r2 θ = 1 2 (3.5)2 (2.042) = 12.51 m2 . WebExample 1: If the angle of the sector with radius 4 units is 45°, then find the length of the sector. Solution: Area = ... In the following diagram, a sector is shown in yellow colour.

WebArea of Sector = θ 2 × r 2 (when θ is in radians) Area of Sector = θ × π 360 × r 2 (when θ is in degrees) Area of Segment The Area of a Segment is the area of a sector minus the triangular piece (shown in light blue here). … WebFind the area of the yellow sector of thecircle with a given radius of 5 units. Use pi = 3.14. a) 3.925 units squared b) 19.625 units squared c) 3.125 units squared d) 39.25 units … 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. iphone passcode crack tool
