I can help you with some of these questions
1. The Great Wall of China is 13,170.696
2.how many feet are in a mile= 5,280= 1 mile
3. 19,536,000=3700 miles
Area 1 = 175.84
area 2 = 156.30
area 1: A=(pi)r^2 x 140/360
in this case we would use the degree of the entire circle and the degree of the sector since it is not given.
area 2: A=(pi)r^2 x 280/360
in this case we would use the degree of the entire circle and the degree of the sector since it is not given.
