Step-by-step explanation:
The equation for the volume of a cone is...
Since we are using 4 for the radius we can plug that in, along with 12 for the height and 3.14 for pi.
So the equation with everything plugged in will be...
Now we can solve.
The volume of the cone is...

Answer:
B. 87
Step-by-step explanation:
The first thing is to calculate critical z factor
the alpha and the critical z score for a confidence level of 90% is calculated as follows:
two sided alpha = (100% - 98%) / 200 = 0.01
critical z factor for two sided alpha of .01 is calculated as follows:
critical z factor = z factor for (1 - .01) = z factor for (.99) which through the attached graph becomes:
critical z factor = 2.33
Now we have the following formula:
ME = z * (sd / sqrt (N) ^ (1/2))
where ME is the margin of error and is equal to 75, sd is the standard deviation which is 300 and the value of z is 2.33
N the sample size and we want to know it, replacing:
75 = 2.33 * (300 / (N) ^ (1/2))
solving for N we have:
N = (2.33 * 300/75) ^ 2
N = 86.86
Which means that the sample size was 87.
