A cylindrical well is dug out whose diameter is 14 m and height is 20 m is half filled with water. Find the volume of water inside the well.
Answers
Given :-
- Diameter of cylindrical well = 14 m.
- Height of cylindrical well = 20 m.
To Find :-
- Find the volume of water inside the well ?
Solution :-
we know that,
- Radius = Diameter/2
- Volume of cylinder = π * (radius)² * height .
putting values we get,
→ Volume = (22/7) * (14/2)² * 20
→ Volume = (22/7) * 7 * 7 * 20
→ Volume = 22 * 7 * 20
→ Volume = 3080 m³.
then,
→ Half of volume = 3080/2 = 1540 m³.
now,
→ 1m³ = 1000 litre
→ 1540 m³ = 1000 * 1540 = 1540000 litre (Ans.)
Hence, the volume of water inside the well is 1540000 litre .

Answer:
Step-by-step explanation:
Well is in a cylindrically shape.
Diameter =14m
Height = 20m
Radius = Diameter /2
= 14 /2 = 7m
Volume of cylinder = πr²h
= 3.14 × 7² × 20
= 3.14 × 49 ×20
= 3077.2 m³
Water is filled half of in the well
Volume of the well is 3077.2m³
Volume of water is 3077.2 /2 =1538.6m³
1 m³ = 1000 l
1538.6 × 1000 = 1538600 l
