Question 1157157
n, number of degrees of central angle


{{{(n/360)pi*5^2=32}}}

{{{n=32*360/(25pi)}}}

{{{n=460.8/pi}}}---------------angle of the sector, degrees


Length of just the curved part:
{{{(n/360)2*pi*5}}}

{{{((460.8/pi)/360)*2*pi*5}}}

{{{(460.8/(360pi))2*5*pi}}}

{{{460.8/36}}}---------------length of the curved part.


Perimeter:  {{{2*5+460.8/36}}}, and you can compute the value.
