For this case we have that by definition, the arc length of a circle is given by:

AL = \frac {x * 2 \pi * r} {360}

Where:

x: Represents the angle between AB. According to the figure we have that x = 90 degrees.

r = 7.9 \ cm

So:

AL = \frac {90 * 2 \pi * 7.9} {360}\\AL = \frac {90 * 2 * 3.14 * 7.9} {360}\\AL = \frac {4465,08} {360}\\AL = 12.403

Answer:

12.4\ cm

So So sorry, I answered so late xd

The mean can be found by adding all the numbers then dividing it by the amount of numbers

The mean for team A is about 7.7 
and the mean for team B is about 7.6
So they're A.) About the same

To find the range find the biggest number then subtract it by the smallest
Team A: 12,0 ; 12 - 0 = 12
12 is the range
Team B: 12,3 ; 12 - 3 = 9
The answer is B.) <span>much greater for conference a than for b</span>
