dimensions of the pipe
length=h=0.14m =14cm
inner radius=r=0.09m=9cm
let the thick ness of the pipe = x cm
outer radius=R=r+x=9+x
given
volume of the pipe=748cm^3
outer volume-inner volume=748
pi*h(R+r)(R-r)=748
22/7*14*(9+x+9)(9+x-9)=748
(18+x)x=(748*7)/(22*14)
x^2+18x=17
x^2+18x-17=0
solve it u can get x value
