We need the height of the cone
what we do is we know that when height is 10, V=something, so solve for the diameter is at that point and compare it to 24, the full height
sorry if confusing
V=(1/3)hpir^2
when h=10
160pi/3=1/3(10)pir^2
ties 3 both sides
160pi=10pir^2
divide by 10pi
16=r^2
sqrt both sides
r=4
at that point, the radius is 4
the real radius of the ful is 24/2=12
4/12=1/3
it is 1/3 full
if 1/3=160pi/3cm
2/3=320pi/3cm^3
needs 320pi/3 cm^3
There's this many Packages and this many cans in each package right? All you have to do is multiply the number of cans and the number of packages to get the total number of cans.
For the cost is the same thing. If you know the cost is this much, multiply the amount of packages×The cost of each package which will give you the total cost. Good luck

Answer:
C) The expected value is -$40, so the man should not buy the warranty.
Step-by-step explanation:
The total cost to the man is expected to be the total of the amount he pays for the warranty and any amounts he gets because he has the warranty ...
-$100 +600×0.10 +0×0.90 = -$40
The expected value of the warranty is -$40. Based on that alone, the man should decide not to buy it.

<em>Comment on warranties</em>
The expected value of a warranty to the buyer is <em>always negative</em>. That is how warranty companies make their money. Clearly, <em>expected value</em> is not the only criterion that should be considered.
Complete Question:
