Answer 6

well, we can assess a few things and do some subtraction since i cant recall any formulas for this stuff

Answer 7

we are essentially subtracting a small cone from a larger cone

Answer 8

can we get the height?

Answer 9

1/3 B^2 h - 1/3 b^2 (h-k)

h-k is the height of the frustrum, and h is the representative height of the pyrimad that was chopped

Answer 10

i think we can determine height but that depends on what you are able to use: trig? or just pythag?

Answer 11

Answer 12

i got h as 20.8

Answer 13

by this formula \[l^2=h^2+(r2-r1)^2\]
