PLEASE HELP ME! my answers are ( look above) oh and no i didnt just put any random answer these are actually my answers -_-

Answer 1

Did you have fun guessing on these?

Answer 2

Why not show us your work, and we can identify where you went wrong.

Recall that for a sphere, v = 4/3 πr^3
for a prism, v = Base * height
for a pyramid, v = 1/3 Base * height
for #4,5, you need to describe the solids
for solids, the ratio of volumes id the cube of the ratio of sides.
