I’m stuck and I don’t know what to do someone help please

For the second question, you’re finding the volume of a cylinder. The formula is V = (pi)(r^2)(h) so we will plug in what we know. Half of a diameter is the radius so 6/2 = 3. It says radius squared so 3^ 2 = 9. We can also see the height is 9 cm so plug that in. For all of these formulas, we must use 3.14 for pi so plug that in also.
V = (3.14)(9)(9)
V = 254. 34 cm cubed

I don’t have time to help with the other questions but I hope this helps you know how to use the cylinder volume formula

Yes of course i will indeed you with your problem.

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3
