To solve this problem you must apply the proccedure shown below:
1. Clear the radius from the formula for the circumference of a circle and substitute values, as following:

2. Substitute the radius calculated into the formula for calculate the surface area of the sphere:

The answer is: 
Pi times 0.8 = 2.513274123 ( one trip )
2 times 2.513274123 = 5.02654826
So the answer is 5.02654826 and you’ll round it to 5 miles

Answer:
3w+7
c^2 + 4c - 3
Step-by-step explanation:
8v+w+7-8v+2w
8v-8v +w+2w +7
0+3w+7
3w+7
4c^2+6c-3c^2-2c-3
4c^2-3c^2 + 6c-2c -3
c^2+4c-3
