If the length of the cylinder is measured as `25mm` and mass of the cylinder is measured as `50.0gm` find the density of the cylinder `(gm//cm^(3))` in proper significant .

Explanation

`rho=(m)/(((pid^(2))/(4))l)=((0.53xx10^(3))xx4)/((3.14)(1.70xx10^(-3))^(2)(50xx10^(-2)))g//m^(3)=4.7xx10^(8)(2S.F.)` .
