Answer:
Both/Neither.
Step-by-step explanation:
For the circle, the area is π(6)^2= 36π. 3/4 of that is 27π. Now, for the ring, area of outer circle is 36π. The area of inner circle is 9π. So, area of ring is 27π. That means, both will take the same amount of paint.
(5400 bulbs)/(72 bulbs/min) = 75 min
It would take 75 minutes for the machine to make 5400 light bulbs.
