✰✰|| Given ||✰✰
- 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
