#9.08# units

Explanation:

Assuming that the angle is in Degrees.

We know, #s = rtheta#

Where , #s# = The length of the arc,

#r# = The length of the radius.

and #theta# = The angle made at the centre by the arc, in radians.

So,
'
According to the formula,

#s = 13 xx (40 xx 2pi)/(360)#

#rArr s = 13 xx (2pi)/9#

#rArr s = 9.08# units (Round to 2 d.p.)

Hope this helps.
