To find the mass, we first have to calculate the volume.
Inner radius = 24/2 = 12cm = r
Outer radius = 28/2 = 14cm = R
Volume of the pipe = Volume of outer cylinder - Volume of inner cylinder
= πR^2h - πr^2h
= πh (14^2 - 12^2)
= πh × (14 - 12) (14 + 12)
= 22/7 × 35 × 2 × 26
= 22 × 5 × 2 × 26
= 5720 cm^3
Now, 1 cm^3 has mass of 0.6 g
5720 cm^3 = 5720 × 0.6 = 3432 gms
Thus mass of the pipe is 3432 gms.
