At what scale will the plan of the Institute be drawn, if we know the main door has a width of 3.40 m., and in the plan we have measured with the ruler of 6.8 cm.?

i think that you should ask google for the answer to that problem because if we don't know it google does

what is the answer to this

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
