Answer:
V = 32/3 pi
Step-by-step explanation:
The volume of a sphere is given by
V= 4/3 pi r^3
We know the radius is 2
V = 4/3 pi (2)^3
V = 4/3 pi (8)
V = 32/3 pi
Answer:
Your answer is B
Step-by-step explanation:
The lowest number is 4, therefore it cannot be C.
Now you'll have to cross out numbers on both sides and your mean will be 9 because you'll have to add 8 and 10 together and 18 divided by 2 is 9.
Next, put a line between 8 and 10, now the 8 side is the lower quartile and the 10 side is the greater quartile.
For the lower quartile, add 7 and 7 together, divide 14 by 2 and the lower quartile is 7.
For the greater quartile, add 11 and 13 together, that's 24, divide 24 by 2 and that's 12.
Lowest: 4
Mean: 9
Lower quartile: 7
Greater quartile: 12
Highest: 14
Therefore your answer is B and not A or C.
