do you mean 900 times Pi?
-------------------
(4/3)*Pi*R^3 = 900(Pi)
(4/3)*Pi*R^3 = 2,827.43
R^3^= 2,827.43/4.19
R^3 = 674.80
R = 8.77
----------------
Circumference = Pi*2R = Pi*2(8.77) do the math to get your answer
-------------------
If 900 times Pi is not the right number, use the correct number and follow these operations to get your answer.
