Question 320917
A piece of string fits exactly once around the perimeter of a square whose area is 144. 
Rounded to the nearest whole number, what is the area of the largest circle that
 can be formed from the piece of string?
:
The side of square = {{{sqrt(144)}}} = 12
:
We know the circumference of the circle = the perimeter of the square 4(12)
Find r of the circle
{{{2*pi*r}}} = 48
r = {{{48/(2*pi)}}}
r = 7.639
:
A = {{{pi*7.639^2}}}
A = 183 sq/units
