What simple shapes do you see here? Do you know the relevant volume formulas? If we calculate the volumes of the simple shapes, how do we get the volume of the shape in question?QUESTION :

I don't know how to answer this, please provide me how to do it, and not the answer, thanks.

Please check the formula.I know how to get the volume of a cylinder prism with just the radius & the height/length.
V = π • r2 • R
The work above is incorrect.So you have really 2 cylinders #1 is a big one and #2 is the one inside (the hole in the big cylinder)
The formula for cylinder volume is:
V = πr2H
Cylinder #1
V= π*((12+6)/2)*43
V=3.14*81*43
V=10942
Cylinder #2
Go ahead solve for the v of this one r=6 H=43
To get the final volume
Vfinal= V#1-V#2
Good luck!
The work above is incorrect.
The diameter of the outer cylinder do = 12+6+6 = 24
Volume of the outer cylinder Vo = π * (do/2)2 * h = π * 144 * 43
The diameter of the inner "hole" cylinder di = 12
Volume of the outer cylinder Vi = π * (di/2)2 * h = π * 36 * 43
Volume of the hollow cylinder Vo - Vi = π * 144 * 43 - π * 36 * 43 = π * 108 * 43 cm3
finish it....
Please tell me, EXACTLY where (which line? which term?) would you need more explanation?I'm very sorry for the confusion, but do you think you could break down this work a little more to me, like explain it a bit more? I'm not that good at math and just trying to finish this stupid school stuff.
