<h3><u>Radius as function of volume is:</u></h3>
<em><u>Solution:</u></em>
<em><u>The volume of cone is given as</u></em>:
Where,
r is the radius
h is the height
From given,
height = 20 inches
From formula,
Rearrange , so that r is alone in left side of equation
Substitute h = 20
Thus, radius as function of volume is:
The third table is the answer.
x=-5 => y=-5-6=-11
x=-8 => y=--8-6=-14
y=-7 => y=-7-6=-13
4:polygon
5:heptagon and trapoziod or parallelogram
At first, let us solve The equation
We will subtract 4 from both sides
Then let us square both sides
Subtract 2 from both sides to get the value of x
You have two choices with 14
Which one will you choose?
To answer this you must know does this value including the domain or not
Let us try this value for x in the equation if the left-hand side equals the right-hand-side then the value is not extraneous
Since the right-hand side has the same value, so 14 is not extraneous.
So the correct answer is the third choice.
