Question

The perimeter of a sector of a circle of radius 5.8 is 27.2m find the area of sector

Answer 1

Perimeter of sector = 27.2 m

Radius of sector = 5.8 m

Length of the arc of the sector

Length of the arc of the sector (l) = Perimeter - 2(radius)

Length of the arc of the sector (l) = Perimeter - 2(radius) = 27.2 - 2(5.6) = 27.2 - 11.2

Length of the arc of the sector (l) = Perimeter - 2(radius) = 27.2 - 2(5.6) = 27.2 - 11.2= 16 Area of the sector

Length of the arc of the sector (l) = Perimeter - 2(radius) = 27.2 - 2(5.6) = 27.2 - 11.2= 16 Area of the sector = lr/2

Length of the arc of the sector (l) = Perimeter - 2(radius) = 27.2 - 2(5.6) = 27.2 - 11.2= 16 Area of the sector = lr/2 = (16 × 5.6) / 2

Length of the arc of the sector (l) = Perimeter - 2(radius) = 27.2 - 2(5.6) = 27.2 - 11.2= 16 Area of the sector = lr/2 = (16 × 5.6) / 2 = 8 × 5.6

Length of the arc of the sector (l) = Perimeter - 2(radius) = 27.2 - 2(5.6) = 27.2 - 11.2= 16 Area of the sector = lr/2 = (16 × 5.6) / 2 = 8 × 5.6= 44.8 m2
