Answer: C) 2 dimensions; flat surface of length and width, but no depth
One way to think of a plane is to think of a flat sheet of paper that extends infinitely in all directions. The paper must be kept flat without any bends.
Answer:
If the number is infinite then it's irrational
We can get the circumference of any circle in terms of the radius with this formula. C = 2

r.
Where r is the radius of the circle.
And we will use 3.14 for

.
Plug in all the values.
C = 2 * 3.14 * 2
C = 12.56
So, the circumference of the circle is 12.6 inches when rounded to the nearest tenth.
The answer is c 28 because it is going by plus 4 <span />
