Answer:
72 parts
Steps:
Convert the 4 hours into minutes. There are 60 minutes in an hour. Therefore, 4 hours = 240 minutes.
Divide 240 minutes by 40 minutes. This equals 6. Therefore, the machinist can produce the 12 parts 6 times in 4 hours.
Finally, multiply the 12 parts by the 6 times he can produce. Therefore, the machinist can produce 72 parts in 4 hours.
Answer:
61.26
Step-by-step explanation:
The formula for area of a cylinder is 2πrh+2πr2. Since the distance across the top is 3, that would be the diameter and the radius would be 1.5. When you input 1.5 as the radius and 5 as the height you get the answer shown.
