Understanding π You can find<span> the </span>radius<span> of a circle from either its area or its circumference -- the distance around the edge of the circle. To do either of these calculations, you will need to use the number π. π, or pi, is equal to the circumference of a circle divided by its diameter.

Answer:
We see that the only complete time-distance pair indicates that she walked 6.4 miles in 2 hours. If she walked at a constant speed, we can conclude that girl walked 3.2 miles in 1 hour. Using this speed, we can find the remaining values in the table. The easier entry to complete is finding out how far she walked in 5 hours: 5 hours⋅3.2 miles/hour=16 miles. To find out how long it took to walk 8 hours we can either notice that 8 is half of 16, so it took half the time to walk half the distance or we can divide 8 miles by 3.2 miles per hour to find that it took 2.5 hours
