Answer:
First figure is a hexagon
second figure is a dodecagon
third figure is a decagon
Step-by-step explanation:
We can classify each figure by how many sides it has.
the first one had 6 sides. a six sided polygon is known as a hexagon
the second one has 12 sides. a 12 sided polygon is known as a dodecagon
the third one has 10 sides. a 10 sided polygon is known as a decagon
Answer:

Step-by-step explanation:
In order to find the area of a circle we multiply π by the radius, and to find the radius of a circle we have to look at the line that stops directly in the middle of the circle.

Once we then have the radius, we simply multiply the radius, (with an exponent of 2) by π and then we will have our answer. Of course, round if needed.

Hope this helps.

FYI: Im a bit confused on what this question is asking but I am responding based on what I believe the question is asking.
The point 100 spaces to the left of -1 would be (-101,0) and the point 100 spaces to the left of -1 would be (100,0).
The point(s) 100 spaces to the left of -1 would be (- infinity, -1) and the point(s) 100 spaces to the right would be (-1, infinity).
