Question

a cylinder cal tank has a radius of 154 cm It is half filled with water till a height of 3 M if some more water to a height of 4.5 metre is poured in to it what will be the increase in the volume of the water
​

Answer 1

Answer:

Radius of cylindrical tank = 154cm = 1.54m

height of water =3m

if height is 4.5 m then let the volume be v

volume of cylinder v = 22/7 *r *r*(H-h)

                                 =22/7*1.54*1.54*(4.5-3)

                                 =22/7*2.3716*1.5

                                  =22*0.3388*1.5

                                 =11.1804 m3
