Answer:
12.56
Step-by-step explanation:
The formula of a circle's circumfernce is C = d pi
so we know that r = 2 and d = 2r
d then = 2 * 2 = 4
4 * pi (taking 3.14) = 12.56
therefore circumfernce = 12.56

Answer:
44.8
Step-by-step explanation:
this is the answer
The sum of the interior and exterior angle need to equal 180 degrees.
Let the exterior angle = X
You are told the interior angle = 38x +24
Now you have x + 38x +24 = 180
Combine like terms:
39x +24 = 180
Subtract 24 from each side:
39x = 156
Divide both sides by 39:
x = 156 / 39
x = 4
The number of sides is found by dividing 360 by the exterior angle:
360 / 4 = 90
There are 90 sides.
That answer is -18 dfffdffdf
