  • Diameter of sector = 40 mm

  • Angel of sector = 120°

✰✰|| To Find ||✰✰

  • Area of sector

|| Formula Use ||

  • Area of sector = ½ r² ∅

|| Solution ||

Area of sector = ½ r² ∅

Area of sector = ½ × ( 40mm/2 )² × 120°

⇒ Area of sector = ½ × ( 20mm )² × 120°

⇒ Area of sector = ½ × 400mm² × 120°

⇒ Area of sector = ½ × 48000mm²

⇒ Area of sector = 1× 24000mm²

⇒ Area of sector = 24000mm²

Area of sector is 24000mm²
