Answer:
Both the zoo-keepers are correct.
Step-by-step explanation:
The first zoo keeper uses the equation:
x - 41.5 = 13.5
⇒ x = 13.5 + 14. 5 = 55
Now, the second zoo- keeper uses the equation:
41.5 + 13.5 = x
⇒ x = 55
Both use x = 55.
Find <em>n</em> :
P = a + b + c
63 = n + (4n - 8) + (2n + 8)
63 = (n + 4n + 2n) + (-8 + 8)
63 = 7n
n = 63 ÷ 7
n = 9
Sides :
1.) n = <u>9</u>
2.) 4n - 8 = 4(9) - 8 = 36 - 8 = <u>2</u><u>8</u>
3.) 2n + 8 = 2(9) + 8 = 18 + 8 = <u>2</u><u>6</u>

See the attached image below for the drawing.
Point G = midpoint of segment DE
Point H = midpoint of segment FD
---------------------------------------------------------------------------------
Add up the x coordinates of points D and E, then divide by 2. So you should get (x1+x2)/2 = (0+2)/2 = 2/2 = 1. This is the x coordinate of point G.
Repeat for the y coordinates of D and E. So we have (y1+y2)/2 = (7+0)/2 = 7/2 = 3.5
Therefore point G is located at (x,y) = (1, 3.5)
---------------------------------------------------------------------------------
These steps will be repeated to find the midpoint H
Add up the x coordinates of F and D, then divide by 2. So, (x1+x2)/2 = (6+0)/2 = 6/2 = 3
Do the same for the y coordinates: (y1+y2)/2 = (7+0)/2 = 7/2 = 3.5
Point H is located at (3, 3.5)
In order to solve for this, we need to find the volumes of both the cylinder and cone described.
In order to find the area of the cylinder:
We use the equation V=
So, V=
The volume of the cylinder is therefore approximately <span>1809.56
For the cone:
V=
So, V=
Thus, the volume of the cone is 113.1
We add these volumes together to derive the solution, which is 1922.66
