Question

The penguin exhibit at a zoo has a raised circular island that is surrounded by water. The diameter of the island is 20 meters. One penguin swims half way around the island before hopping out.

How far did the penguin swim?

Answer 1

Answer: 31.4 meters

3.14 X 20 = 62.8 meters

The penguin swims half way around:

62.8 / 2 = 31.4 meters
