Answer:
k = 8
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 32 when x = 4, then
32 = 4k ( divide both sides by 4 )
8 = k
Answer:
Volume of the given cone is 1107.6 cubic feet.
Step-by-step explanation:
Formula to get the volume of a right circular cone is,
V =
Here r = radius of the circular base
h = height of the cone
Now we put the values in the given formula
Volume = [ radius = ]
=
= 1107.55
≈ 1107.6 cubic feet
Therefore, volume of the given cone is 1107.6 cubic feet.
Answer:
2112
Step-by-step explanation:
we find the area of the base first
which is 16*12/2 because it is a right triangle
16*12/2 = 96
then we multiply the base by the height
22*96 = 2112
as a note, remember, prism volume is all base * height
