How far did the penguin swim?
Give your answer in terms of pi.

Answer 1

Answer:

31.42 m

Step-by-step explanation:

Since, the path is circular :

The distance traveled can be I tin by taking the Circumference of the path :

Circumference, C = πd

d = diameter = 20 meters

C = π * 20

Since penguin swam. Only halfway around the island.

Hence, distance traveled = 1/2 * C

= 1/2 * 20π

= 31.42 m
