Area=height times base (for some prisms including cylinders)
vcylinder=hpir²
h=height
therefor pir²=base area
vcylinder=height times aeraofbase

 

given
h=9
v=324pi
324pi=9(basearea)
divide both sides by 9
36pi=areabase

the area of the base is 36pi square cm (put 36 in the blank since the pi is already there)

The volume of a cylinder is V = pi*r^2*h.

Here 324*pi cc = (pi*r^2)*h, where h = 9 cm
                                                                     324*pi cc
Thus,    the area of the base,  (pi*r^2) , is -----------------
                                                                         9 cm, which simplifies to

base area = 36<span>π cm^2</span>

Consider the following two studies reported in the New York Times:
Setler [38]

Answer:

Step-by-step explanation:

1) Not neccesarily. There might be a small correlation, however, you cant predict if a person will have breast Cancer only due to their bone mineral density because the probability for a woman to have breast cancer is pretty low (below 5%). According to the data given, women with high bone density are just 3 times more likely to have breast cancer, thus, the probability will be just 15%. There might be a correlation but you need more information than just the mineral bone density to predict breast cancer, there might be other causes that are not related with mineral bone density.

2) It is impractical to conduct such an experiment. The problem lies in the fact that you cant fix the amount of mineral bone density a woman have. 2 women with different BMD might be quite different in different aspects one from the other, so you wont be completly sure that the cancer was caused in one case just because of the mineral bone density alone. An ideal experiment will have identical bodies differing on mineral bone density alone, but that is in practice impossible to do.
