Step-by-step explanation:
Given radius of the glass jar, R = 8 cm
Diameter of the sphere = 12 cm
Radius of the sphere, r = 12/2 = 6 cm
When the sphere is removed from the jar, volume of water decreases.
Let h be the height by which water level will decrease.
Volume of water decreased = Volume of the sphere
R2h = (4/3)r3
82h = (4/3)63
h = (4/3)×6×6×6/(8×8)
= 18/4 = 9/2 = 4.5 cm
Hence the height by which water level decreased is 4.5 cm.
Answer :
Given radius of the glass jar, R = 8 cm
Diameter of the sphere = 12 cm
Radius of the sphere, r = 12/2 = 6 cm
When the sphere is removed from the jar, volume of water decreases.
Let h be the height by which water level will decrease.
Volume of water decreased = Volume of the sphere
R2h = (4/3)r3
82h = (4/3)63
h = (4/3)×6×6×6/(8×8)
= 18/4 = 9/2 = 4.5 cm
Hence the height by which water level decreased is 4.5 cm.
