00:00To create the circle I used GeoGebra, the circumference tool, center and radius to calculate the perimeter of the multiplied circumferences
00:13Pi times the double of the radius which is 6 and the result is 18.85 and to calculate the surface is Pi times radius squared
00:28The radius is 3 so squared is 9
00:33So Pi times 9 is 28.27 cm squared
