The shape of the well will be cylindrical.
Depth (h1) of well = 14 m
Radius (r1) of the circular end of well =
Width of embankment = 4 m
From the figure, it can be observed that our embankment will be in a cylindrical shape having outer radius (r2) as and inner radius (r1) as.
Let the height of embankment be h2.
Volume of soil dug from well = Volume of earth used to form embankment
Therefore, the height of the embankment will be 1.125 m.
Circumference of the circular pool: 20*pi feet
pi*6.52 - pi*52 = 54.19247327 or about 54 square feet.
A circle's circumference is the product of Pi and its diameter, so a diameter can go around a circumference approximately 3.14 times.
Diameter of circle: 70/pi = 22.28 mm rounded to two decimal places
It is: (pi*radius)+(diameter)
The circumference is obtained by multiplying the diameter by pi.
30 feet
Perimeter = pi*diameter so 200*pi = 628.32 metres.
267ft
Circumference of the circular pool: 20*pi feet

If a jogger jogs around a circular track with a diameter of 275 meters in 14 minutes his average speed (pace) is 1.0285 meters per second.
The answer will depend on what the 12 mm measures. If the object is 12 mm in diameter, it is 37.7 mm around.
pi*6.52 - pi*52 = 54.19247327 or about 54 square feet.
A length of approx 18.85 feet.
It is:: 200 times pi = which is about 628.319 meters rounded to 3 decimal places
A diameter is a characteristic of a circular shape, and has no intrinsic size. A big shape will have a big diameter and a small shape will have a small one. For example, the earth's equator has a diameter of approx 12800 kilometres while a pin has a diameter of around 1 millimetre.
