Question

5m,how many full bags of wheat can be emptied if the space requrired for wheat in each bag is 2.1m^3(take pie=3.14)

Answer 1

Given

r = 4.2m,

h = 3.5m


Volume of the drum = (πr2h)m3 = 3.14x(4.2)2x3.5

Volume of each bag of wheat = 2.1 cubic metre

Number of bags = Volume of drum

Volume of a bag = 3.14x4.2x4.2x3.5

2.1 ≈ 92 bags

Answer 2

Space required for each bag = 2.1 m^3
=>Radius of drum =4.2 m
=>Height of drum = 3.5 m
=>Volume of drum(cylinder) = πr^2h

======>3.14 x 4.2 x 4.2 x 3.5
=>>>>>=>3.14 x 4.2 x 4.2 x 3.5
=======>3.14 x 61.74
=======>193.8636m^3
No. of bag=>193.8636 ÷ 2.1
=>>>>>>>>=>92.316
=>>>>>>>>=>92 bags(approx)
