All right, so the volume of a right circular cone is represented by this formula.
00:06
And so they basically say, well, r, your radius is 3x, and your height is 2x.
00:11
So how would this kind of simplify with that given information? and so let's just go ahead and plug in this formula with, ooh, that is not the best looking pie symbol i've ever drawn.
00:22
All right.
00:23
R is 3x.
00:24
I'll put that in parentheses, raise the second power, and multiplied this whole thing by 2x.
00:30
All right, so if i do 3x squared, you basically this squared kind of gets distributed to both.
00:38
So 3 squared is 3 times 3 is 9.
00:41
X times x is x squared.
00:44
And again, this is multiplied all by 2x.
00:48
I'm going to go ahead and do a little bit of simplifying here because i can see right now, 9 times a third...
