Volume of a cone: 1/3

r²h
r is the radius (diameter ÷ 2) and h is the height.
Find the radius first using the diameter: 2

÷ 2 = 1.25
Now plug in the numbers into the formula.
1/3

1.25²10 = <span>16.4

The volume of the cone is 16.4 cubic feet.
Answer:
x
≈
16
Explanation:
Remember Sine of an angle is
opposite side
hypotenuse
So let the hypotenuse be
x
:
sin
(
47
°
)
=
opposite side
x
sin
(
47
°
)
=
12
x
To solve for
x
, divide
sin
(
47
°
)
by
12
:
x
=
12
sin
(
47
°
)
x
≈
16
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality

and to get it, we simply need two points off of the straight line, hmm let's use the ones in the picture below.
