Step-by-step explanation:
Given : Radius= 18cm, angle of a sector = 60°, area of a sector = ?
Solution:
Area of a sector = Angle of a sector / 360° × πr^2
= 60° / 360° × 3.14 × 18 × 18
= 1 / 6 × 3.14 × 18 × 18
= 1/ 6 × 3.14 × 324
= 1 / 6 × 1017.36
= 169.56
Therefore area of a given sector = 169.56 sq. cm

Answer:
Solution:
Area of a sector = Angle of a sector / = 360° x^2
= 60° / 360° x 3.14 x 18 x 18
= 1/6 x 3.14 x 18 x 18
= 1/ 6 x 3.14 x 324
= 1/6 x 1017.36
= 169.56
