Question 1120368
Dimensions of the metal sheet, x and y


{{{system(xy=800,cross(y*(pi*x^2)=400))}}}

<s>Solve this system.</s>


cross section circumference is {{{x=2pi*r}}}.

{{{r=x/(2pi)}}}


cross section area is {{{pi*r^2=pi(x/(2pi))^2=x^2/(4pi)}}}.


{{{system(xy=800,y*x^2/(4pi)=400)}}}
Solve this system.
