Into a circular drum of radius 4.2 m and height 3.5m, how many full bags of wheat can be emptied if the space required for wheat in each bag is 2.1 cubic m. `(Take pi=3. 14)`

Explanation

Radius`=4.2m`
Height`=3.5m`
Volume of bag`=2.1m^3`
Volume of drum`=pir^2h`
`=3.14xx4.2xx4.2xx3.5`
Number of bags`=` Volume of drum`/`volume of bag
`=>N=(3.14xx4.2xx4.2xx3.5)/2.1`
`=>N=92.316=92`
`therefore` Number of bags`=92`
