#3 - #9 need a look at the diagrams, which of course we can't post here
#10 - #12 look good
#13 ----- need diagram, can't tell which numbers go where
#14 --- need diagram
#15 , I guessed what you meant, looks ok
#16
18/15 = x/5
15x = 90
x = 6
#17
volumes of similar objects are proportional to the cube of their corresponding sides
x/1920 = 18^3/24^3 = (3/4)^3 = 27/64
64x = 27(1920)
x = 27(1920)/64 = 810
#18
SA of sphere = 4πr^2 <----- you must know that!
= 4π(25) = 100π = 314 to the nearest m^2

I know there are more questions but, you know the laziness. I'm just going to give you 12 answers, not all 19, sry.
Hope this helped! :D
Just a warning, my questions may be different so the answers may also be different because yes, they do change the questions once in a while, so don't comment that I probably didn't give you a good grade.
-Ya'llMakeMeFacePalm._.
-Ya'llMakeMeFacePalm._.
maybe not completely but hey it'll b a passing grade
some question's lengths and heights get changed up as well so i'd recommend using surface area, volume, etc, calculators on as many as you can
also, for number 2 its actually a cone
