Answer:
all you need to do is to multiple
1/15 because you add all the blocks together and it gives you 15 and there is only 1 blue block so it will be a 1/15 chance of getting it
The volume of a cone is

since V=65.94 and r=3, you just plug it in and solve for h which results to 6.996cm
So just convert to a common form
I will convert to decimal since 2 of them are already decimals
to conver 1 and 3/7 to decimal, just divide 3 by 7 using a calculator
1 3/7=1.43...
so 1.38, 1.43, 1.40
the greates is .43 then .40 then .38 so the order is
least to greatest
1.38, 1.4, 1 3/7 or D
I believe the answer would be D. Because, 10*12= 120 and 400/120= 3.33
Since you are talking about money, you would round up.
Meaning that the answer should be D.
