That's 18 square feet - which is 2 square yards.
11 by 9 = 99 square feet and there are 0.09290304 square metres in one square foot. With this information you can now work out the answer.
284.48 cm.
im not exactly sure of what you mean but if you mean there are 5 9foot cicles the distance would be 45ft.
A fifty year old is about 9foot
That depends on the species of crayfish. There are both fresh water and salt water crays ranging in mature sizes from 3 inches to 60 inches. If kept in a fish tank with fish, most of them will grab a lump of fish to eat if they get half a chance. IMO Crayfish not in the wild should be on a plate cooked and ready for eating.
If you are still interested in a price I can tell you that being a 9ft rod, and from a little known maker that you are probably looking at something less than $200.
