b)October
Answer:
Let r represent the radius of the smaller circle and R the radius of the larger circle.
Apply ratios: the radius of smaller circle to radius of larger circle, i.e.
r: R = 3 : 7.
I complete rotation = 360 degrees.
Part 1:
For one complete rotation of the smaller circle, the larger circle is rotated through: (3/7)*(360) = 154.3 degrees
Part 2:
For one complete rotation of the larger circle, the larger circle is rotated through: (7/3)*(360) = 840.0 degrees
This is equivalent to (840/360) = 2.3 rotations
Alternatively, use the ratios:
The number of rotations = R/r = 7/3 = 2.3 rotations

Step-by-step explanation:
The formula to use is F +V -E = 2
F = Faces = 16
V = Vertices = 14
E = edges = Unknown
We can fill in the information we have and solve for edges:
16 + 14 - E = 2
Add 16 and 14:
30 - E = 2
E = 30-2
E = 28
There are 28 edges
