Answer:
3.49 radians
Step-by-step explanation:
The arc length formula is s = rФ, where r is the radius and Ф is the central angle. We know s and r and need to calculate Ф.
From s = rФ we get Ф = central angle = s/r
Here, that central angle Ф is (31.4 cm) / 9 cm = 3.49 radians
There is a total of 24 students in the class.
The probability of choosing a girl is 16/24. Which reduces down to 2/3 or 66%.
The probability of choosing a boy is 8/24. Which reduces to 1/3 or 33%.
So the student has a 66% chance of choosing a girl and 33% chance for a boy.
