Question

A map of a public park shows a circular pond. There is a bridge along a diameter of the pond that is 0.75 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? Round your answer to the nearest hundredth. Use 3.14 for π.

Answer 1

C= πd, where C means circumference and d means diameter. 0.75 is the diameter of the pond, so 3.14 × 0.75 gives you 2.355mi.

You walked the diameter while your friend walked the HALF circumference. (2.355÷2) -0.75 is your answer
