Answer:
The arc length of the entire circle would be 2*PI*9
We need to know the arc length of 1/3 of the circle so we calculate
arc length = (2 * PI * 9) / 3
arc length = 2 * PI * 3
arc length = 6 * PI
arc length = 18.8495559215
Step-by-step explanation:
sqrt(1^2 + 2^2)
There is a 50% probablity that it will land on 1. There is a 30% chance it will land on 5.
