inner radius = r cm
thickness of metal pipe = t cm
outside radius = inner radius + thickness = r + t cm
height = h = 28 cm
Difference of outside CSA - inner CSA = 2*22/7*28 [ (r+t) - r ] cm²
= 176 t cm² = 88 cm²
=> thickness t = 0.50 cm
thickness of metal pipe = t cm
outside radius = inner radius + thickness = r + t cm
height = h = 28 cm
Difference of outside CSA - inner CSA = 2*22/7*28 [ (r+t) - r ] cm²
= 176 t cm² = 88 cm²
=> thickness t = 0.50 cm
