Answer:
1- a circle
2- 5 miles
3- 78.5 sq miles
4- 31.4 miles
5- 235.5 more miles
Step-by-step explanation:
1 - a line in all directions is a circle
2- distance = speed * time
2.5 * 2
5
3- area = pi * radius ^2
3.14 (5)^2
3.14 25
78.5 (area1)
4- circumference = 2 * pi * radius
2 3.14 (5)
3.14 (10)
31.4
5- distance = speed * time
2.5 * 4
10
area = pi * radius ^2
3.14 * 10^2
3.14 * 100
314 ( area2)
remaining area = area1 - area2
314-78.5
235.5
