Answer» Volume of the metallic cylindrical pipe = 748 Cm³ length of the cylindrical pipe h =14 cm external radius of the pipe R = 9 cm let the internal radius of the cylindrical pipe be r cm. therefore the volume of the metallic pipe= π(R1²-r2²)h therefore thickness of the metallic pipe = R-r=9-8=1 cm |
