Question

what is the area is the sector whose diameter is 40mm and angle is 120°​

Answer 1

Answer:

The answer is 24000mm²

Step-by-step explanation:

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
