<u>Answer:</u>
- In 10 rotations, we will travel 44000/7 ft. or 6285.714 ft.
<u>Explanation:</u>
- 1 Rotation: 2πr
- => 1 Rotation: 2 x 22/7 x 100
- => 10 Rotations: 2 x 22/7 x 100 x 10
- => 10 Rotations: 44/7 x 100 x 10
- => 10 Rotations: 44000/7
- => 10 Rotations = 44000/7 = 6285.71428571 ft. (Using Calculator)
- => 10 Rotations = 44000/7 = 6285.714 (Estimated)
<u>Conclusion: </u>
Therefore, in 10 rotations, we will travel 44000/7 ft. or 6285.714 ft.

I believe the answer is: D. There are three economic classes: the rich, the poor, and the middle class.
The separation between these classes is based on their ownership of wealth&resources. The poor are those who barely have enough resources to keep living,
The middle class are those who can comfortably fulfil their basic needs while having a little bit of surplus that they can put into saving , while the Rich are those who had abundance of wealth & resources, to the point where they would not able to spend it in their lifetime.
Driven in part by economic concerns, and in part by frustration with the straitened social conditions of the South, in the 1870s African Americans began moving North and West in great numbers. In the 1890s, the number of African Americans moving to the Northeast and the Midwest was double that of the previous decade.
