Question 1128923
A lead ball is formed into a circular sheet. Find diameter of sheet.

Ball diameter; 2 in. 

Sheet thickness; 0.01 in. 

A ball is a sphere. 

=============
Vol of the sphere = 4pi*r^3/3 = 4pi/3 cubic inches.
----------
Volume of the sheet = pi*r^2*h where h = thickness of 0.01"
V of sheet = pi^r^2*0.01
----
The 2 volumes are equal
4pi/3 = pi*r^2*0.01
0.01r^2 = 4/3
r^2 = 400/3
r =~ 11.54"
d =~ 23.09 inches
