Question

lf each bag containing rice occupies 2.1m^3 of space, then the number of full bags which can be emptied into a cylindrical drum of radius 4.2m and height 3.5m is​

Answer 1

each bag containing rice occupies 2.1m3

r of cylinder=4.2m

h of cylinder=3.5m

no.of bags ×space occupied by each bag= volume of cylinder

let no.of bags be n

n×2.1m3=πr2h

n=22×4.2×4.2×3.5/7×2.1

n=407.484m3

n=406484

no. of bags =406484
