Geometry so it has shapes and can't post them so its a screen shot image

I pretty sure on these 2 below but not the others

12. B
13.C
14. C
15. C

12) 11.7X5.4X9.4 = 593.892 ....B

13) We want cu yds 1 yd = 3ft and 1 yd = 36 in
so 15ft/3= 5yds and 3in/36= 1/12 yd
5 X 5X 1/1 = 2.0833333 yds^3 X $46/yd^3 = $95.83 .........C

14) V cyl= π r^2 * h = π*(2.2)^2* 12 = 58.08π.........B

15) V cyl= π r^2 * h = π*3^2*6 = 54π...........C

12. B,
13. C,
14. B, (2.2 squared X 12) They want it in pie formation, meaning that the number multiplied by pie gives the volume :), volume = 182.46 / pie = 58.08.
15. A, Not sure at all on this... but the only option that made sense (this is due to them giving the perpendicular height of the cylinder whilst its actually slanted)

:)

14 is wrong. Remember the formula (V = pi * (r^2) * h).

The rest of your work is solid, though. Especially number 13--good job watching your units.
