<PRE><B>Question 306107</B>
A cylindrical glass 10 cm tall and 8 cm in diameter is filled to 1 cm from the top with water. If a golf ball 4 cm in diameter is dropped into the glass, will the water overflow? 
----------------------------
The height of the glass is not relevant.
-----------------------------
The space in the glass is
{{{V = pi*r^2*h = pi*16*1 = 16pi}}}
---------------------
The volume of the ball is:
{{{4*pi*r^3/3 = 4*pi*8/3 = 32pi/3}}}
--------------
The space is greater, so no overflow
