Question

A well whose diameter is 7m has been dug deep and earth dug out is used to form an embankment around it. If the height of the embankment is 1.5m? Find the width of embankment

Answer 1

Answer:

here is your answer please mark brainlist

Volume of well = Volume of embankment

So pie*(3.5)2 *22.5 = pie *(x)2 * 1.5 - pie * (3.5)2 * 1.5

On solving we get x = 14 m

So width of the embankment = 14 - 3.5 = 10.5 m

Step-by-step explanation:

Answer 2

Answer: here is your answer plz mark brainlist

Step-by-step explanation:

Volume of well = volume of embankment

So pie *(3.5)2*22.5=pie*(x)2*1.5-pie*(3.5)*1.5

On solving x = 14 m

So weigth of the embankment = 14 - 3.5 = 10.5
