Question

a bag of wheat grain contains 2.5m³.How many bags can be emptied to fill a circular drum of diameter 7m and height 5m

Answer 1

Answer:

Step-by-step explanation:

First, we have to find the volume of the drum.

V=pi*r*r*r*h

=55m3

No. of bags emptied=55/2.5

=22 bags

Thus, 22 bags should be filled in the drum

Answer 2

Answer:79 bags

Step-by-step explanation:

Volume of cylindrical drum= πr²h

=22/7×7/2×7/2×5

=197.5m³

Total bags can be emptied=197.5m³/2.5m³

=79 bags
