Question 796224: a metal pipe has thickness 3 cm and outer radius 10 cm. find the volume of metal required to cast the pipe. if the length of pipe is 5 meter
Answer by Cromlix(4381) (Show Source): You can put this solution on YOUR website!
External volume = Pi*r^2*h
External volume = Pi*10^2*500
External volume = 157079.63 cm^3
Inner volume = Pi*r^2*h
Inner volume = Pi*7^2*500
Inner volume = 76969.02 cm^3
External volume - Inner volume
157079.63 - 76969.02
= 80110.61 cm^3
Hope this helps.
