no, pi = 3.14 (about)
If you mean 3*pi then it is greater than 9
r2*pie=circumference 9(9)*pie 81*pie 254
(pie)(diameter)=(circumference) (pie)(9)(2)=18(pie)=56.549
1/9 doubled is 2/9. Consider a pie cut into 9 pieces. 1/9 is one piece of pie. Double that top get 2 pieces of pie or 2/9.
since c of the pool is 18 then 2pieR = 18 /2 pieR=9 /pie R=9/pie the radius is 9/pie

Don't know about a 9 inch but there are 1.5 quarts in a 9.5 inch pie plate.

175% would be a pie graph and then 3/4 of another one. See the related link, "175% pie graph" for a picture.
pie x D = Pie x 9 = 28.3 ( to 1 dp) The circumfrence is roughly 3 times the diameter
