V = \pi r^{2} h

Volume of material of pipe,

V = (volume of outer cylinder) - (volume of inner cylinder)

= \pi r_{1}^ {2} l - \pi r_{2}^ {2} l

= \pi (12^{2} - 10^{2}) 100

= \pi (144-100)100

= 4400\pi cm^{3}.

The volume of steel is 13828.57 cubic cm

Step-by-step explanation:

Outer radius of pipe R = 12 cm

Inner radius of pipe r = 10 cm

Length of pipe = 100 cm

Volume of steel = Outer volume - Inner volume

Volume of steel =\pi R^2 h - \pi r^2 h

Volume of steel =\frac{22}{7}(12^2-10^2)(100)

Volume of steel =13828.57 cm^3

Hence The volume of steel is 13828.57 cubic cm
