#1 ok
#2 ??
#3 ok
#4,6 can't be sure from description
#5 ok if the radius is 12
#7 ok if you include the base, but that seems kinda stupid, since the bin is Presumably) sitting on the ground.
#8 A
#9 I didn't get any of the choices, so I guess the description was insufficient
#10 ok
#11 A
#12 B
It's really hard to figure out just what some of your objects look like.
If you disagree with some of my choices, show why you think so. I might have made a mistake, after all...

Yeah. All of your answers are correct. By the way, I really like your thinking and understanding of your problems. My advice is for you to ask your parents or your siblings( if you have any) for help. If they don't know then you could go online and ask a tutor. There are many people who could help you. Just giving out advice.
