If the total bill is $85, and you want to leave a 15% tip, then you can calculate it as follows:
85 * 15%
= 85 * 15/100
= 85 * 0.15
= 12.75
The amount that should be left as a tip is D. $12.75.
        
             
        
        
        
Answer:
31.4 inches
Step-by-step explanation:
If a circle is inscribed in a square then diameter of circle inscribed is same as  side as of square.
In the given problem it is given that side of square is 10 inches.
So diameter of  circle inscribed is 10 inches
we know radius of circle is half of  diameter of  circle 
Thus, radius of circle inscribed = diameter of  circle/2 = 10/2 = 5inches.
Expression to calculate circumference of circle is given by 
where r is the radius of circle.
Thus circumference of  circle inscribed is 

Thus, circumference of  circle inscribed is  31.4 inches
