Ler radius of sphere be r cm and radius of cylinder be R cm.
From the question , we have
r cm =9 cm
R cm = 18 cm
Consider the water level rose be H cm.
Now,
Volume of sphere = 4/3 π r3 cubic units
= 4/3 π× 9× 9× 9 cubic units .
Volume of cylinder = π ×18×18× H cubic cm
.
From Archimedes principle we get
4/3 π 9×9×9 = π ×18×18×H.
→ H = 3.
Thus, level of height increased = 3cm
Volume of sphere = 972π cm3
