Question

An empty oil drum weighs 58kg. If its height is 1.4m and radius 0.5m, find its mass when filled with oil of density 0.9g/cm^3​

Answer 1

weight=58kg

from radius and height volume=1.1m^3

assuming it to be. cylinder

so now density =58/1.1=around 58

density of oil=0.9

and vol. of cylinder =1.1 so

mass=density*vol.=0.9*1100000

so ans. 990000 g= 990kg

plz mark as brainliest ..

Answer 2

volume of the drum= πr^2h

22x.5^2 x 1.4/7=I. Im3=ll00000cm3

Weight: Ilooooox 0.9=99oooogm.

=990kg

Wt .ofdrum +oil=990+58=1048kg
