Answer 2

The height of embankment is 5.25 m

Step-by-step explanation:

Diameter of well = 12 m

Radius of well =$\frac{12}{2}=6 m$

Depth of well = 21 m

Volume of well = $\pi r^2 h = \frac{22}{7} \times 6^2 \times 21$

Width of embankment = 6 m

Radius of embankment = 6+6=12 m

Let the height of embankment be h

Volume of embankment = $\pi r^2 h = \frac{22}{7} \times 12^2 h$

Volume of well = Volume of embankment

$\frac{22}{7} \times 6^2 \times 21 = \frac{22}{7} \times 12^2 \times h\\\frac{6^2 \times 21}{12^2}=h\\5.25= h$

Hence The height of embankment is 5.25 m
