Question

A well of diameter 3m is dug 14 deep.the eartg taken out of it has been spread evenly all around itin the shape of a circular ring of wudtg 4m to forn an embakment fund the height

Answer 1

Answer:

1.125

Step-by-step explanation:

radius of well =3/2 =1.5m and depth is 14m

radius Of Embankment = 1.5+4 =5.5m

let height be h

volume if embank = volume of well (cylinder)

πr2h = π[(5.5)2- (1.5)2] into h

= π(1.5)2 into 14

[30.25-2.25]into h = 2.25 into 14

h = 2.25 into 14/28 = 1.125
