To find the volume of the cone use the formula:
3.14r^2 h/3
Final Answer:
20.93 cubic units
You have not given us any of the steps that Ricardo took to simplify the
expression, and you also haven't given us the list of choices that includes
the description of his mistake, so you're batting O for two so far.
Other than those minor details, the question is intriguing, and it certainly
draws me in.
If Ricardo made a mistake in simplifying that expression, I'm going to say that
it was most likely in the process of removing the parentheses in the middle.
Now you understand that this is all guess-work, because of all the stuff that you
left out when you copied the question, but I think he probably forgot that the 3x
operates on everything inside the parentheses.
He probably wrote that 3x (x-3) is
either 3x² - 3
or x - 9x .
In reality, when properly simplified,
3x (x - 3) = 3x² - 9x .
To find the total length of the two copper pipes, we need to add them together.
2 5/12 + 3 7/12 = 5 12/12
Since 12/12 = 1 or a whole, we can simplify this further.
5 12/12 = 6
Hope this helps!
Answer:
60
Step-by-step explanation:
180=(x+30)+(4x)
Ok, combine like terms. That'll give you
180=5x+30.
Now solve for x. X is going to equal 30.
Then substitute 30 for x in the angles. One angle will be 60 and the other will be 120.
60 is smaller than 120 so that's your answer.

I don't get the question a bit but I hope this makes sense
