The radius of the completed cone is
... 18×(300°/360°) = 15
The height of the completed cone is found from the Pythagorean theorem:
... 15² + h² = 18²
... h = √99 = 3√11
The volume is given by
... V = (1/3)πr²·h = (1/3)π·15²·3√11
Dividing this value by π gives 225√11 cubic units.
The answer is 13/25 13 is odd so it can't be evenly divided by anything so it is in its simplest form
The probability that the mean clock life would differ from the population mean by greater than 12.5 years is 98.30%.
Given mean of 14 years, variance of 25 and sample size is 50.
We have to calculate the probability that the mean clock life would differ from the population mean by greater than 1.5 years.
μ=14,
σ=
=5
n=50
s orσ =5/
=0.7071.
This is 1 subtracted by the p value of z when X=12.5.
So,
z=X-μ/σ
=12.5-14/0.7071
=-2.12
P value=0.0170
1-0.0170=0.9830
=98.30%
Hence the probability that the mean clock life would differ from the population mean by greater than 1.5 years is 98.30%.

There is a mistake in question and correct question is as under:
What is the probability that the mean clock life would differ from the population mean by greater than 12.5 years?
Answer:
2/3 probability that the answer choice which rohit selects for question is wrong.
Step-by-step explanation:
Completing the question :- what is probability that the answer choice which rohit selects for question is wrong.
Answer :
Since there are 3 possible options provided out of which 1 is correct. So probability of correct answer is 1/3. probability of incorrect answer is 2/3.
So, there is 2/3 probability that the answer choice which rohit selects for question is wrong.
Answer:
0.6%??
I did 3 divided by 500 and got 0.006 then moved the decimal places to transform the decimal to fraction which ends up being 0.6%
