A hollow cylindrical tube is 3.5 m long if its inner and outer radii are 7 cm and 7.7 respectively then find the volume of the material used in making the pipe.
Gave me right solution step by step. I will really mark your answer as brainlist.
Answer of this question is 11319 cm cube. but you have to gave me right solution step by step.

Answer:
Volume of material used in making the pipe = \bold {48069\ cm^3}48069 cm3
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 350722×7×7×350
=17150\ cm^317150 cm3
Outer volume of cylinder = πr²h
= \frac{22}{7}\times 7.7\times 7.7\times 350722×7.7×7.7×350
= 65219\ cm^365219 cm3
Volume of material used in making the pipe = Outer volume of cylinder - Inner volume of cylinder
= 65219 - 17150
=\bold {48069\ cm^3}48069 cm3
