Step-by-step explanation:
where is the question huh ?

This may look scary, but all you have to do is distribute, first:

Now it's much easier (remember to distribute the negative):

So, the entire thing simplifies to
-2c. NEAT!
V=PiR^2H/3
Pi = 3.14 (use pi symbol on calculator)
R is the radius if the cones bottom
H is the height of the cone
1/92
what is the number we can divide both 45 and 4140 by. it is 45. divide.
45/45=1
4140/45=92
the answer is 1/92
