Answer:
ANSWER
Radius of cylindrical tank =154 cm=1.54 m
Height of water =3 m
If height is 4.5 m then let the volume be v
Increase in volume of cylinder (v)=
7
22
×r

×(H−h)
Increase in volume of cylinder (v)=
7
22
×1.54×1.54×(4.5−3)
Increase in volume of cylinder (v)=

×2.3716×1.5
Increase in volume of cylinder (v)=22×0.3388×1.5
Increase in volume of cylinder (v)=11.1804 m

As we know that the water is inside the tank and the thing which we will have to find out is the Volume.
The formula to find the volume is πr^2h
We will take π as 22/7
Radius = 154 cm
We will change it in Meters as the height is in meter.
= 1.54 meters
Note:- You can also change the height which is in Meters in Centimetres
= 22/7 × (1.54)^2 × 3m
= 22/7 × 2.37 × 3m
= 22.37 approx
The Volume when water is not filled is 22.37 meters approximately
After the Water is filled.
= 22/7 × (1.54)^2 × 4.5
= 22/7 × 2.37 × 4.5
= 33.51 approx
Now we will subtract
33.51 - 22.37
= 11.14 meters
= 11.14m^3
