  1. About .206901426 feet.


  2. There is an equation for circle area that goes "circumference = diameter x 3.14". So, if you divide the circumference by 3.14, you'll get 0.4140127388 feet which is the diameter, but you don't want the diameter. You want the radius. Since the radius is always equal to half the diameter of the circle, you can just divide 0.4140127388 feet by 2 and get 0.2070063694 feet.
