Question

4. A well of diameter 3 mis dug 14 m deep. The earth taken out of it has been spread evenly
all around it in the shape of a circular ring of width 4 m to form an embankment. Find the
height of the embankment.​

Answer 1

Answer:

In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere

Answer 2

Answer:

99/88

Step-by-step explanation:

Diameter=3m

Radius=3/2m

Height=14m

Volume=πr^2h

π3/2×3/2×14= 63/2π=99m^3

Diameter of embankment=3+4+4=11m

Let height of embankment=H

Volume of embankment=πR^H

π11/2×11/2×H

121/4π×H=1331/14H

Volume of well= Volume of embankment

99=1331/14H

H=99×14/1331

H=99/88
