Edging needed = pi*13 feet
97.5 yards
133.33 square yards of carpet
13.5 x 81.8 = 1104.3 square feet = 122.7 square yards
9.26 cubic yards for every inch of depth.
Edging needed = pi*13 feet
40.8 feet
26 feet plus twice the length.
A length of approx 18.85 feet.
6 yards x 1 yard = 18 feet x 3 feet. So the bed will have a perimeter of 2*(18+3) = 42 feet. Using 12-inch stones, this will require 42+4 = 46 stones. [The +4 are for the four corners]. The inner layer has a perimeter of 2*(20+5) = 50 feet Add the 4 corners and it will require 54 stones. All together, than makes 46+54 = 100 stones, which @2.32 per stone, will cost 232 units of currency.
The answer depends on how much what. Fencing or edging is related to perimeter; turfing or netting is related to area.
90 feet squared of carpet is needed.
It depends how deep you want it.

625 times 0.5 = 312.5 cubic feet will be needed
