Using 3.14 for pi, how do you get 355 as the volume for a cylinder?

X = cylinder volume<br />350/717.25 = .4879749<br />so .4879749 =355/X<br />4879749*X =355<br />355/4879749 = X<br />X = 727.49643<br />727.49643 = cylinder volume Your welcome

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
