Swimming half way around implies half of the circumference.

Circumference = pi x diameter

C = pi x 20

C = 20pi

20pi / 2 = 10pi

You swam 10pi meters = 31.42 meters.

Hope this helps!! :)

Circumference is c=dxpi

C= 20x3.14

C= 62.8

Halfway around the lake it 31.4

Hope this helps :)

Wittaler [7]
To find mean/average it's fairly simple!! :)

The first thing you should do is add up the first numbers -
* 20 + 15 + 16 = 51 :)
* 16 + 19 + 17 = 52

Now divide each of the scores by the amount of numbers there is -
* 20 (1) 15 (2) 16 (3)
* 16 (1) 19 (2) 17 (3)

51 ÷ 3 = 17 (Rolanda's Average Score)
- Which # is bigger?
52 ÷ 3 = 17.3 (Jetta's Average Score)
