pie x D = Pie x 9 = 28.3 ( to 1 dp) The circumfrence is roughly 3 times the diameter
r2*pie=circumference 9(9)*pie 81*pie 254
(pie)(diameter)=(circumference) (pie)(9)(2)=18(pie)=56.549
for the surface area:4 times pie times radius squared for volume:4/3 times pie times radius cubed
9. Circumference equals 2 times Pi times the radius. C=2(pi)r. "r" for radius. So if your circumference is 18 times pi, then you do 18 divided by 2, which gives you a radius of 9.
pie x D = Pie x 9 = 28.3 ( to 1 dp) The circumfrence is roughly 3 times the diameter
If you mean 3*pi then it is greater than 9
r2*pie=circumference 9(9)*pie 81*pie 254
take pie times pie and times the diameter
(pie)(diameter)=(circumference) (pie)(9)(2)=18(pie)=56.549
pie times 3 = Gavin Preller rocks
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
Circumference is 2 times pie (which is often rounded to 3.14) times the radius. The result is 56.52 inches.

Cherry Pie costs 10 cents in the Colonial Times.
Don't know about a 9 inch but there are 1.5 quarts in a 9.5 inch pie plate.
