Answer:
It depends on the speed and acceleration of the plane.
But it's approximately 2 hr
Circumference = 2 · π · r or π · d
Radius = 7.8
7.8 × 2 = 15.6
15.6 × 3.14(π) = 48.984
Circumference = 48.984 rounded = 49
Area = π · r²
Radius = 7.8
7.8 × 7.8 = 60.84
60.84 × 3.14(π) = 191.0376
Area = 191.0376 rounded = 191

Answer: 12,600
Step-by-step explanation: 5% of 10,500 is 525. Multiply that by 4 and get 2,100. Add that to 10,500 and you get 12,600.
Answer: In point-slope form it's y-2=2/3(x-1)
