A hollow metal pipe whose internal and external diameter are 2.8cm and 6.3cm respectively is 3.5 long. a) calculate the volume of the metal used to make the pipe in cm3

The volume of the metal used to make the pipe is approximately 545.2 cm3.
wrong again!
3.5π(3.15^2 - 1.4^2) = 67.5 cm^3
3.5π(3.15^2 - 1.4^2) = 67.5 cm^3
Wrong again, the robot tutor was not even close
outer radius = 3.15
inner radius = 1.4
volume of material of pipe = π (3.15^2 - 1.4^2)(3.5)
= 87.55 cm^3
I assumed the 3.5 was 3.5 cm, the units were not given
outer radius = 3.15
