#1: The central angle of each slice would be found by dividing the total central angle of a circle (360°) by the number of slices (8), so:
Each slice would have a central angle of 45°.
#2: This question is vague, since the arc can be measured in degrees or inches. The degree measure of the intercepted arc would be 90°. The length in inches of the intercepted arc could be found using the formula:
So, in your case, it'd be:
#3: The circumference of any circle is found by the equation
wher r is the radius. So in your case it's 
which is 
.
As for the equation of the circle when graphed, it's:
