Answer:
See the top left picture. the answer is there
Step-by-step explanation:
I will assume big cylinder is A. and small one is B.
Volume A = 424
Volume B = 188
the difference is 424 - 188 = 236.
If you see the top left picture, the side is divided by 2. Left side 188 and right side 188. Next step is, we can see that the shape is only difference at the top (for diameter), so we must slice it diagonally, means we need to divided it again by 2. So the remaining is 188/2 for both left and right.
Now add all the volume together (look at the shape)
Cylinder B + remaining left + remaining right = 188 + 94 + 94 = 306
