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
