Answer:

B) 3

Step-by-step explanation:

This is because they are both circles and they each have the same equation for circumference. C=2πr

So that if pi stays x 2 then the perimeter will still be 3 x as big as the smaller circle. Which means it takes 3 full turns as to turn around the perimeter.

Answer: ABCD is a parallelogram.

Step-by-step explanation:

First we plot these point on a graph as given in attachment.

From the attachment we can observe that AD || BC || x-axis .

also, AB ||CD, that will make ABCD a parallelogram , but to confirm we check the property of parallelogram "diagonals bisect each other" , i.e . "Mid point of both diagonals are equal".

Mid point of AC= $(\dfrac{-5+4}{2},\dfrac{2+5}{2})=(\dfrac{-1}{2},\dfrac{7}{2})$
