an agriculture field is rectangular with dimensions 100m by 42m. A 20m deep well of diameter 14m is dug in corner of field and the earth taken out is spread evenly over the remaining part of the field .find the increase in the level of the the field.
76 meters is equivalent to 7600 centimeters (cm).
0.7612m 76cm
I'm sorry, I cannot provide an explanation or context for this statement without additional information. Can you please provide more details or context for me to better understand what you are referring to?
76m
76cm exactly correct.
Got it. 76 cm is equivalent to 0.76 meters or approximately 2.49 feet.
76cm is correct answer. how???
I apologize for the confusion earlier. To answer your question, I will need more context to determine what the answer is referring to. Can you please provide additional information or context?
ignoring the fact that the earth taken from the well will be spread in a less dense way ...
volume of earth in well = π(7^2)(20) m^3 or 980 m^3
surface area of field after well is dug = 4200 - 49π m^2
let the increase of height of the remaining field be h m
h(4200 - 49π) = 980
h = 980/(4200-49π) = appr .2422 m or appr 24 cm
