Answer:
B
Step-by-step explanation:
Formula for finding the volume of a cone: 
From the question, we can tell that the height, h, is equal to 2d or 4r.
h = 4r.
Substitute h into the volume formula:
Rearrange to get the final equation of:
Answer:
1) 0.30
2) 0.308
Step-by-step explanation:
1)
Interest Frequency
High 30
Medium 40
Low 30
Total frequency=30+40+30=100.
The relative frequency of student with high interest can be computed by dividing the frequency of high interest to the total frequency.
R.f of high interest=30/100=0.30
2)
Monthly Commission Frequencies
600-800 3
800-1000 7
1000-1200 11
1200-1400 22
1400-1600 40
1600-1800 24
1800-2000 9
2000-2200 4
Total frequency=3+7+11+22+40+24+9+4=120
The relative frequency of earning 1600 or more computed by dividing the frequency of earning 1600 or more to the total frequency.
R.f of earning more than 1600=24+9+4/120=37/120=0.308
