Area of shaded sector is 163 cm²
The area of the shaded portion can be obtained using the formula for area of a sector ;
- Area = θ/360 × π × r²
- r = radius = 12
- θ = 130
Substituting into.the formula ;
Area = (130/360) × 3.14 × 12²
Area = 163.279 cm²
To the nearest whole number, Area of shaded sector is 163 cm²
