plzz answer me its urgent

Answer 1

Hey !!! ^_^


Here is your answer

⬇️⬇️⬇️⬇️⬇️⬇️⬇️

In rectangle ( field)

l = 20m

b = 14 m

In Cylinder ( well )

r = 7/2

h = 10

__________________________

As per questions ..


Volume of well = volume of earth level rise in the field ..

Volume of Well = ∏r²h

Volume of Earth level rise in the field = l × b × h

∏r²h = l × b × h

$\frac{22}{7} \times \frac{7}{2} \times \frac{7}{2} \times 10 = 20 \times 14 \times h \\ \\ 11 \times 7 \times 5 = 20 \times 14 \times h \\ \\ h = \frac{11 \times 7 \times 5}{20 \times 14} \\ \\ h = \frac{11}{8} m \:$


So the level of earth rise in the field = 11/8m .
