Answer:
Height= 18cm
Step-by-step explanation:
Curved surface area = 2πrh
108π = 2 * π * 3 * h
108π = 6πh
h= 108π ÷ 6π
h= 18cm
Total students = 16
1. Total 9th graders = 3
Probability of being 9th grader = 3/16
2. Total that like comedy = 6
Probability = 6/16 = 3/8
3. 3 like action so 16-3 = 13 do not.
Probability = 13/16
4. 1 10th grader likes comedy out of 5 10th graders
Probability = 1/5
5. 0 out of 3 12th graders like comedy.
Probability = 0
6. 0 like action out of 3
Probability = 3/3 = 1
7. Yes the probabilities are different.
