​

Answer 1

Answer:

.....................

Answer 2

The volume of metal used is 704000 cubic cm

Step-by-step explanation:

Height of cylinder = 10 m =1000 cm

Inner radius r= 55 cm

Thickness  = 2 cm

Outer radius R = 55+2=57 cm

Volume of metal used = Outer volume - Inner volume

Volume of metal used =$\pi R^2 h - \pi r^2 h$

Volume of metal used =$\frac{22}{7}(57^2-55^2)(1000)$

Volume of metal used =$704000 cm^3$

Hence The volume of metal used is 704000 cubic cm
