Question

in a circular drum of radius 4.2 m and height 3.5 m. how many bags of wheat can be empty if space in each bag is 2.1 cubic meter

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

2.1 ≈ 92 bags

Answer 2

AnswEr:

We have ,

• r = 4.2 m
• h = 3.5 m

_______________________________

$\therefore$ $\mathfrak\pink{Volume\:of\:the\:drum\::}$

$\tt = (\pi {r}^{2} h) {m}^{3} = 3.15 \times(4.2) {}^{2} \times 3.5 \: {m}^{3}$

___________________________

Volume of each bag of wheat = 2.1 cubic metre

$\therefore$$\mathfrak\orange{Number\:of\:bags\::}$

$\tt = \frac{volume \: of \: drum}{volume \: of \: a \: bag} \\ \\ \tt = \frac{3.14 \times 4.2 \times 4.2 \times 3.5}{2.1}$

$\implies$ $\sf\blue{Number\:of\:bags}$

$\tt = 3.14 \times 8.4 \times 3.5 = 92.316 \\ \\ \tt = 92 \: bags \: nearly$
