= $sqrt ( 9 + (pi/3)^2)$

Distance between points $A(5, 5pi/4), B(8,11pi/12)$ using Distance formula is as below:

= $sqrt ( (5-8)^2 + ((5pi)/4 – (11pi)/12)^2$

= $sqrt ( (-3)^2 + ((15pi)/12 – (11pi)/12)^2$

= $sqrt ( 9 + ((4pi)/12)^2)$
= $sqrt ( 9 + (pi/3)^2)$

What is the distance between (5 ,(5 pi)/4 )(5 ,(5 pi)/4 ) and (8 , (11 pi )/12 )(8 , (11 pi )/12 )?
