Question 1067933
Full circle arc is  {{{2pi}}}.
Your given central angle is  {{{3pi/2}}}.


Complete circumference of your given 16 foot radius is  {{{2*pi*16}}}.


Your central angle on your given circle is an arc length  {{{highlight(((3pi/2)/(2pi))(2*pi*16))}}}, and this just needs to be simplified and computed.
