Answer:
9 cm
Step-by-step explanation:
Use the cone volume formula, V = 
r²
Plug in the volume and radius, and solve for h, the height:
V = r²
27 = (3²)
27
= 9
3 =
9 = h
So, the height of the cone is 9 cm
C) y= -x+5
explain:
y-2=-x+3
y= -x+3+2
so y= -x+5
In a geometric sequence dividing any term by the term before it yields the common multiplier.
Then x/(x+8) = (3x-8)/x
Solving for x: reduces to x^2-10x +16 factor into (x-2)(x-8)
Then x = 2 or 8
2 produces a sequence of -2, 2, -2 ...
8 produces a sequence of 4, 8, 16 ...

Answer:
GH=15
Step-by-step explanation:
HK= FK/2= 16/2= 8
Using pythagoras theorem in triangle GHK,
GH²= GK²-HK²
= 17²-8²
= 225
GH= √225
=15
