Question

19) 13) A cylindrical tank has a radius of 154 cm. It is filled with water till a height of 3 metres. If some more water to a height of 4.5 metres is poured into it, what will be the increase in the volume of water?​

Answer 1

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

×r

2

×(H−h)

Increase in volume of cylinder (v)=

7

22

×1.54×1.54×(4.5−3)

Increase in volume of cylinder (v)=

7

22

×2.3716×1.5

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

Increase in volume of cylinder (v)=11.1804 m
