Question

Help with these 2 questions? I'm so close to being done, and these are holding me back!

Answer 1

For similar figure,
(side ratio) ^3 = Vol ratio
that is
(s1)^3 V1
------ = ---
(s2)^3 V2
Now, put s1 = 5, s2 =3 and v2 = 108 into the equation
Can you find the volume for the larger cylinder?

Answer 2

Would it be 180? Or is my math completely off? Haha.

Answer 3

I'm afraid it's not...
5^3 / 3^3 = V / 108
V = (125 / 27) x 108

Answer 4

Oh! Okay, so I got 500.04.

Answer 5

I got exactly 500...Anyway,,
Hmm ... Sorry that I can't help you with question 20 because I don't how what a point matrix is :(

Answer 6
