Question

The thick of a metallic tube is 1 CM and its outer radius is 11cm find the mass of such 1 meter long tube if the density of the metal is 7.5 g per cubic cm

Answer 1

$\it\huge\mathfrak\red{answer:-}$]

vol of cylinder = 22/7 (14^2-13^2) 49 cm^3

density= mass/volume

mass = 8* vol of cylinder = 4158 gm

Answer 2

vol of cylinder = 22/7 (14^2-13^2) 49 cm^3

density= mass/volume

mass = 8* vol of cylinder = 4158 gm
