Question

if r, r are the outer and inner radii a hollow pipe respectively and t is the thickness then
R =
inner CSA of the pipe =
outer CSA of the pipe =
TSA of the pipe =
volume of the pipe =​

Answer 1

Step-by-step explanation:

If R, r are the outer and inner radii respectively and t is the thickness then R = r + t, r = R - t, t = R - r. The volume of the material = π(R2 - r2) × Height. The inner curved surface area = 2πr × Height, the outer curved surface area = 2πR × Height.
