Answer:
Vol of cylinder=22/7×1.4×1.4×8
= 1232/25
=49.28cm^3.
d=m/v
= 369.9/49.28
=7.50.

Answer:
7506kg/m^3
Explanation:
Density is defined as mass per unit volume.
mass =369.6g or 0.3696kg
volume of cylinder =πr^2h
where r=1.4cm or 0.014m
h=8cm or 0.08m
volume =4.92×10^-5m^3
density=mass/volume
=7506kg/m^3
