Please help with this one
Dear Student,
Given : A cylindrical can with radius = 3.5 cm
And when a sphere is placed in a can, the water just covers the sphere . Given that the sphere just fits into the can , So
Radius of sphere = 3.5 cm
And
Height of can = Height of water after sphere in the can = Diameter of sphere = 7 cm
And can is open from one side , So
Total surface area of can in contact with water =
Here ,
Volume of sphere = Volume of water rise
Let level of water rise = h m
So,
So,
Level of water rise = cm
Therefore ,
The depth of the water in the can before the sphere was put into the can = 7 - = cm ( Ans )
.
Regards
