Answer:
Step-by-step explanation:
Calculating the volume of a cylinder is very similar to determining the area of a prism. You can ... Recall that the area of a circle is equal to pi times the radius squared. ... V = Π(3.6)2(4) Here we started by replaced r with the radius and h with the height. ... V = 5400Π mm3 ← If you are

Answer:
2.5
Step-by-step explanation:\
We can solve it like this
4 + x = 6.5
6.5 - 4 = x
6.5 - 4 = 2.5
SO
4 + 2.5 = 6.5
Answer: 641
I believe this is correct, but I did it fast so unsure.. hope this helps :)
A) The empirical rule tells you the probability of being within 1 standard deviation of the mean is 68%.
b) The probability that the sample mean falls within 3 standard deviations* of the mean is 99.7%.
___
* The standard deviation of the sample mean is 1/√9 = 1/3 of the standard deviation of an individual sample. Hence the same limits (90-110) now cover 3 standard deviations of the sample mean.
