Answer:

0.245

Step-by-step explanation:

The population proportion refers to the proportion of the total population. In the scenario above, the population proportion is the proportion of all adult population in the United States who are obese.

Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius. Use pi on your calculator
Virty [35]
ANSWER
V=254.47in^3

EXPLANATION

The volume of a cylinder is given by the formula:

V=\pi \: {r}^{2} h

The given cylinder has diameter 6. This means that, the radius is

r = \frac{6}{2}

r = 3cm

The is height is

h = 3r

h = 3(3) = 9cm

We substitute the values into the formula to obtain;

V=\pi \: {3}^{2} \times 9

V=81\pi

V=254.46900494

The volume is 254.47in^3 to the nearest hundredth
