For this case we have that by definition, the perimeter of a circle is given by:
Where:
r: It is the radius of the circle.
According to the figure, it is observed that the radius of the circle is 2. Then:
Let's remember that we have a quarter circle:
We round and we have that the correct option is 
Answer:
Option A
The attached figure is the image that completes the question
A is correct the y intercept is (0,5)
Answer:
10 m
Step-by-step explanation:
If we draw the diagonal of the rectangle, we form a right triangle where the diagonal is the hypotenuse and the legs are 6 and 8.
This is a well-known Pythagorean triple, which gives the diagonal to be 10 m.
6(4.4) = 6 x 4.4 = 26.4
The one with the parenthesis would be the distributive property. I'm not 100% sure, though. Hope this helps.
