The diameter would be 18! (: Quite a nice even number coming from a decimal! If you need anymore help let me know! (: I hope all is well, and you pass! Good luck, rockstar! (:
divide it by 3.14 to get its radius squared which is a little over 81. find the square root of 81 which is 9. the radius is 9 and the radius is half the diameter so the diameter is 18 units.
