Question

= 481.25 litres.
tron pipe is 21 cm long and its external diameter is 8 cm. If the
hickness of the pipe is 1 cm and iron weighs 8 g/cm", find the
weight of the pipe.
External radius of the pipe = 4 cm.
Thickness of the pipe = 1 cm.
Internal radius of the pipe = (4 - 1) cm = 3 cm.
External volume =(22 4 x 4 x 21 cm = 1056 cm°.
22
Internal volume = 1 4 x3x3 x 21 cm
= 594 cm.
Volume of the metal = (external volume) - (internal volume)
= (1056 -594) cm * = 462 cm.
(462x8)
Weight of the pipe = (462 x 8) g =
kg = 3.696 kg.
