Answer:
I believe its A.
Step-by-step explanation:
Answer:
A ≈ 530 cm²
Step-by-step explanation:
The swept area equals the total area covered by the blade minus the unswept area.
The area of a sector with radius r and angle θ is:
A = (θ / 360) πr²
So the swept area is:
A = (θ / 360) πR² − (θ / 360) πr²
A = (θ / 360) π (R² − r²)
A = (150 / 360) π (21² − 6²)
A ≈ 530 cm²
Answer:

Step-by-step explanation:
Answer:
5 and 48
Step-by-step explanation:
27:45
Simplify the ratio
3:5
The first one must be 5, and option 1 (5 and 48) is the only one with 5.
