Answer: A 24 cm piece of string is cut into two pieces , one piece is used to form a circle and the other piece is used to form a square.
How should this string be cut so that the sum of the areas is a minimum .
:  
Let x = the circumference of the circle
then
(24-x) = the perimeter of the square
:
Find the area of the circle
find r
2*pi*r = x
r =  
Find the area of the circle
A =  
A =  
A =  sq/cm, the area of the circle
:
Find the area of the square
A =  sq/cm the area of the square
The total area
At =  +  
Graph this equation, find the min
Min occurs when x=10.6 cm
cut string 10.6 cm from one end
