Question 1065019
Let {{{ C }}} = the circumference of the circle
I can say:
{{{ ( 3*pi ) / C = 72 / 360 }}}
Multiply both sides by {{{ 360a }}}
{{{ 1080*pi = 72C }}}
{{{ C = 15*pi }}}
----------------
The formula for cicumference is:
{{{ C = 2*pi*r }}}
{{{ 15*pi = 2*pi*r }}}
{{{ r = 15/2 }}}
{{{ r = 7.5 }}} m
