Answer:
surface area is 39
Step-by-step explanation:
add the areas of each geometric figure making up the composite 3D figure.
first 3D figure
2+2+6+6
=16---eq 1
from third 3D figure
4+4+10+5
= 23
from 1 and 2
16+23
= 39
may be!! I'm not sure bout this answer
In decreasing order:
439.612, 439.261, 439.216, 439.126
Volume is 4/3(3.14)(r)^2
the radius is 5.2 ft
because there are 12 in one layer and there are 3 layers
