Answer:
see explanation
Step-by-step explanation:
The area of the shaded portion is the area of the outer circle subtract the area of the inner circle
area of larger circle = πr² ← r is the radius = 11
area = π × 11² = 121π
area of smaller circle = πr² ← r = 9
area = π × 9² = 81π
-----------------------------------------
shaded area = 121π - 81π = 40π m² ≈ 126 m²
Answer:
or 
Step-by-step explanation:
Given


Required
Calculate the area of the sector
When angle is given in degrees, the area of sector is calculated as thus;


becomes






The above is the area in terms of π
Solving further.... (Take π as 3.14)
becomes


Hence, the area of the sector is
