A map of a public park shows a circular pond. There is a bridge along a diameter of the pond that is 0.25 mi long. You walk across the bridge,while your friend walks halfway around the pond to meet you at the other side of the bridge. How much farther does your friend walk?

Question

THANKS!

Answer 1

with a circle of diameter d, half the circumference is πd/2.

So, what's the difference between πd/2 and d? Now plug in your numbers.

Answer 2

C= 3.14 times 0.25 because it says half and diameter puts a line through everything.

3.14 times 0.25 equals 0.785
