the volume of a metallic cylindrical pipe is 748 cm3. its length is 14cm n external radius is 9 cm. find its thickness.
volume of the metallic cylindrical pipe = 748
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 =
thickness of the metallic pipe = R-r=9-8=1 cm
