Answer:
52
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here the sum = 9000°, thus
180° (n - 2) = 9000° ( divide both sides by 180° )
n - 2 = 50 ( add 2 to both sides )
n = 52

To reflect a triangle, just draw the opposite of what it originally looked like, aka mirror image.
Answer:
The cone'll require about 37.5 cm of tubing
Step-by-step explanation:
To do this, we need to know that the volume of the medium will have to be the same volume of the cone that will be printed.
Then, the volume of the cone is:
V = π*r^2*h/3
V = 3.14 * 5^2*8 / 3 = 209.33 cm^3
We can assume that the tubing is a cylinder so:
V = π*r^2*h
The radius is 1 1/3, and this is:
1*3 + 1 = 4/3
Solving for h we have:
h= V/π*r^2
h = 209.33 / 3.14*(4/3)^2
h = 209.33 / 5.58
h = 37.5 cm
