Answer:
36
Step-by-step explanation:
171/(4+0.75) =36
you want it to be in minutes, so calculate the 45 seconds over 60 seconds, which is 0.75. Add that to the 4 minutes, and divide the total number of copies over the time used, and you have speed/minute.
b+3a
MN=AN+AM
AN=0.5*AB
AB=OA+OB=4a+2b
AN=2a+b
AM=OA-OM=4a-3a=a
MN=2a+b+a=3a+b
Circumference of a circle is 2piR
Here R is 3 cm
So C=2pi(3)
C=6pi cm
