Step-by-step explanation:
Increase in volume of cylinder = volume of sphere
Let increase in volume of cylinder be =πr2h, where r is its radius and h is its height.
So, πr2h=34πr3
⇒16πh=34π33 where radius of the cylinder=4cm and radius of the sphere=3cm
⇒h=34×1627=1636=49=2.25cm
∴ water rises by 2.25cm in the vessel.
Hope you all got it
