#11.595units#

Explanation:

#sqrt((x_2-x_1)^2+(y_2-y_1)^2)#

#:.=sqrt((-3-8)^2+((17pi)/12-pi/4)^2)#

#:.=sqrt((-11)^2+((17pi-3pi)/12)^2#

#:.=sqrt(121+((17pi-3pi)/12)^2#

#:.=sqrt(121+((cancel14^7pi)/cancel12^6)^2#

#:.=sqrt(121+((7pi)/6)^2#

#:.=sqrt(121+(7pi)/6xx(7pi)/6#

#:.=sqrt(121+21.99114858/6xx21.99114858/6#

#:.=sqrt(121+483.6106157/36#

#:.=sqrt(121+13.433628#

#:.=sqrt(134.4336282#

#:.=11.595# units to the nearest 3 decimal places
