We calculate for the volumes of each of the wax needed for the candles through the equations presented below.
For cylinder:
V = πr²h
where V is volume, r is radius and h is height.
Substituting the known values,
V = (3.14)(3 in)²(6 in)
V = 169.56 in³
For sphere:
V = 4πr³/3
Substituting the known values,
V = 4(3.14)(3 in)³ / 3 = 113.04 in³
The difference between the two volumes,
difference of volumes = 169.56 in³ - 113.04 in³
<em>difference of volumes = 56.52 in³</em>
Thus, the answer to this item is the last choice.

Answer:
30% members have voted.
Step-by-step explanation:
Given:
Number of members voted = 3
Number of members didn't vote = 7
We need to find what percentage of people voted.
Solution:
First we will find the total number of members in the election.
Now we can say that;
The total number of members in the election is equal to sum of Number of members voted and Number of members didn't vote.
framing in equation form we get;
The total number of members in the election = 
Now we will find the percentage of people voted.
So we can say that;
Percentage of members voted can be calculated by dividing Number of members voted from The total number of members in the election and then multiplying by 100 we get;
Percentage of members voted = 
Hence 30% members have voted.
Y=-7x-5
9=-7(-2)-5
9=14-5
9=9

f(x)=x2+14x+40 => <span>f(x)=x^2+14x+40
Next, complete the square:
</span>f(x)=x^2+14x+ 49 - 49 +40 = (x+7)^2 - 9
Write this in the form y = (x+7)^2 - 9 or y + 9 = (x+7)^2
Comparing this result to y = a(x-h)^2 + k, we see that h = -7 and k=-9
In vertex form, the equation is y + 9 = (x+7)^2 and the vertex is at (-7, -9).
