Given the diameter, the area of a circle is
area = (Pi/4)d2

For your circle, the area is
area = (Pi/4)(10 ft)2 = 25*Pi ft2 ≈ 78.54 ft2

It's simple, refer to the formula of the circle area as follows, S=3.14*R*R
where S: The area
  R: The radius of the circle. Equal to the half of the diameter
when the diameter is given, there you go  
good luck
