Step-by-step explanation:

Given,Height = 3.5 m = 350 cm

Outer radii = 7.7 cm

Inner radii = 7 cm

Inner volume of cylinder = πr²h

= \frac{22}{7}\times 7\times 7\times 350

×7×7×350

=17150\ cm^317150 cm

Outer volume of cylinder = πr²h

= \frac{22}{7}\times 7.7\times 7.7\times 350

7

22

×7.7×7.7×350

= 65219\ cm^365219 cm

3

Volume of material used in making the pipe = Outer volume of cylinder - Inner volume of cylinder

= 65219 - 17150

=\bold {48069\ cm^3}48069 cm
