sin(2*pi) - not pie - is the same as sin(0) = 0
Sin(pi/6) = 1/2 is a true statement [not pie].

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.
Sin(pi/6) = 1/2 is a true statement [not pie].
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
since c of the pool is 18 then 2pieR = 18 /2 pieR=9 /pie R=9/pie the radius is 9/pie
it is thinking over a sin. trying a sin. meaning to sin.
