A regular hexagon is drawn inside of a circle so that each of its vertices touches the circle. The diameter of the circle is 4 centimeters and the perimeter of the hexagon is 12 centimeters. How much longer is the circumference of the circle than the perimeter of the hexagon? (use 3.14 for pi)

the circumference is 4pi
the perimeter is 12
so, 4pi  12 = ? 
The answer for your question is simple, π = 3.14, so, first you multiply 4 by 3.14, then it comes to 12.56, right? Yes. The last thing you need to do is to subtract 12 from 12.56 and you get 0.56! :) Hope this helps! ;)

Find perimeter of a regular hexigon with 6 equal sides and with equal interior angles. That is inscribed in a circle, all vertices touch the circle ) of radius 10.0 meters.
