    Since you give the diameter you desire, I am assuming you want to cover a circular area. Well the area of a circle is 3.14 (pi) times the radius squared. The radius is the diameter divided by 2.
    So:
    Radius = 540/2 or  270 feet
    area = 3.14 x 2702 = 228906 sqft
     
    Now the blocks:
    8"  = .667'
    16" =  1.333'
    area per block = .667 x 1.333 = .889 sqft
     
    228906 / .889 = 257488 blocks
    10% extra recommended for cuts = 25749
     
    25749 + 257488 = 283237 Blocks to cover your area

      Can you clarify this?  First of all, do you have "Cedar blocks" or "cinder blocks" (which are typically 8 x 16 inches). 

      Next, do you need a perimeter wall around a circular area? (where you measure a diameter), or a rectangular area? (where we need more information, such as the length by the width and if it's not perfectly rectangular, then it gets more complicated).

      Next we need to know how high your blocks will be.  If it's just one layer then we need to know that. 

      Then are you filling in the inside area with blocks, or just going around the perimeter?
