Check the picture below.
b)
volume wise, we know the smaller pyramid is 1/8 th of the whole pyramid, so the volume of the whole pyramid must be 8/8 th.
Now, if we take off 1/8 th of the volume of whole pyramid, what the whole pyramid is left with is 7/8 th of its total volume, and that 7/8 th is the truncated part, because the 1/8 we chopped off from it, is the volume of the tiny pyramid atop.
Now, what's the ratio of the tiny pyramid to the truncated bottom?
Answer:
sinθ = y/r sinθ =
cosθ = x/r cosθ =
tanθ = y/x tanθ =
cscθ = r/y cscθ =
secθ = r/x secθ =
cotθ = x/y cotθ =
explanation:
r =
r = 10
x = 8
y = -6
r =
r = 5
x = 4
y = 3
