Answer:
D
Step-by-step explanation:
Use the formula for the SA of a hemisphere.
Now we can find the radius of the hemisphere, which is 15.
Then, we can square that and multiply it by 2 to get 450.
Now, let's use the formula for the Volume of a hemisphere.
Now we can cube 15 and multiply it by 2 to get 6750.
Then we can divide this number by 3.
2250.
So the answer is D.
Based on the table attached, the class boundaries are as follows: 43.5, 49.5, 53.5, 59.5, 63.5, 69.5, 73.5, 79.5.

65-69 7
70-74 1
A. Viewing at the frequency table, we find that the lower class limits of two consecutive classes are 40 and 44, respectively. Thus the class width is:
Class width = 44 − 40= 4
B: One can find the class midpoints by putting the average of the lower and upper class limits. So the midpoint of the first class is seen below:
= 40 - 44 = = 42. In a similar way, we find the rest.
C. The Class boundaries is known to be that which separate the classes removing the class limits. The class boundaries are as follows:
43.5, 49.5, 53.5, 59.5, 63.5, 69.5, 73.5, 79.5
Therefore, Based on the table attached, the class boundaries are as follows: 43.5, 49.5, 53.5, 59.5, 63.5, 69.5, 73.5, 79.5.
