Area of sector POQ = (Angle POQ/360) x πr²
= (40/360) x π(6²)
= 6.28 cm²
= (40/360) x π(6²)
= 6.28 cm²

I apologize for the error in my previous response. Here's the correct solution:
Area of circle PQR = πr² = 72 cm²
r² = 72/π
r ≈ 4.79 cm
Therefore, sector POQ has radius 4.79 cm and central angle 40°.
Area of sector POQ = (40/360) x π(4.79²)
= 3.39 cm² (rounded to two decimal places)
Area of circle PQR = πr² = 72 cm²
r² = 72/π
r ≈ 4.79 cm
Therefore, sector POQ has radius 4.79 cm and central angle 40°.
Area of sector POQ = (40/360) x π(4.79²)
= 3.39 cm² (rounded to two decimal places)
