Find the perimeter of a circle?

Please put a picture of the question because I do not see any circle.

Step-by-step explanation:

Answer with explanation:

x :  3    2    1      -1

y :  8    2    0.5   0.125

Difference between two consecutive Domain values

3-2=1

2-1=1

1-(-1)=2

Ratio of two consecutive y values

So, difference between two consecutive Domain values is not same but range value has a common factor equal to 4.

But still when you plot the points in coordinate plane and join it, you will get the shape similar to exponential curve.

Option B

   No; the domain values are not at regular intervals although the range values have a common factor.
