Answer:
x = 27976.22021
Step-by-step explanation:
10x + .0085x = 280000
Combine like terms
10.0085x = 280000
Divide by 10.0085 on each side
10.0085x /10.0085= 280000/10.0085
x = 27976.22021
Radius of the inner circle = 13.2 ÷ 2 = 6.6 mm
Area of the inner circle = π (6.6)² = 43.45π mm²
Radius of the larger circle = 6.6 + 4.4 = 11mm
Area of the larger cicle = π(11)² = 121π mm²
Area of the washer = 121π - 43.45π = 243.3 mm²
Answer: 243.3 mm²
