answer of your question

Answer 2

Answer :-

→ Area of the shaded region = (θ/360°)π(OA)² - (θ/360°)π(OC)²

→ Area = (θ/360°)π[OA² - OC²]

→ Area = (θ/360°)π[(4 + 3)² - 4²]

→ Area = (θ/360°)π[7² - 4²]

→ Area = (θ/360°) * π * (7 + 4) * (7 - 4)

→ Area = (60/360) * 3.14 * 11 * 3

→ Area = (1/6) * 3.14 * 11 * 3

→ Area = (3.14 * 11)/2

→ Area = 1.57 * 11

→ Area = 17.27 cm² (Ans.)
