ok guys and gals...

how do i work out the inner diameter of a hollow tube???

 

[nik_harsha]

hi ,
find the circumference of the tube 2*pi*r. you will get the radius of the outer portion . now substract the thickness of the tube from that . you will get the inner radius .
simple!

 

[bantamm]

thanks for that, but we are not told the thickness.

that would be too easy...

but thread can be closed as ive solved it i think...!
