Question

find volume of copperuse in a pipe of length 10.5 outer radius 5m an thickness 10m​

Answer 1

Answer:

seems your thickness is 10cm

volume of cylinder= π×r^2×h

=π×10.5×5 ^2

=26.25π

volume of inner cylinder=π×r× r × h

=π×10.5×(5-.1)^2

24.01π

volume of copper =26.25π-24.01π

=22÷7×2.24

=7.04
