Question

6. A solid iron pole consists of a cylinder of height 220 cm and base diameter 24 cm, which
is surmounted by another cylinder of height 60 cm and radius 8 cm. Find the mass of the
pole, given that I cm of iron has approximately 8g mass. (Use
$\pi$
= 3.14)
and radio standing on​

Answer is 892.26 kg now see step by step explanation

$\huge \fbox \green{Solution}$

volume of first cylinder = 3.14×12×12×220

volume of second cylinder =3.14×8×8×60

on solving these two and then adding we get = 111532.8cm cube

mass per cm cube = 8gram

Total Mass= 11532×8=892262.4 gram =892.26 kg
