A 1.27-cm diameter copper (r = 8933 kg/m3, c = 385 J/(kg °C)) sphere is heated in a convection furnace for a very long time so that its temperature becomes equal to the temperature of the air in the furnace at 260 °C. Then, the sphere is removed from the furnace and is placed in a forced convection flow where the heat transfer coefficient h is 17 W/(m2 °C) and where the temperature is 38 °C. The sphere is allowed to remain in the flow for 450 seconds at which time it is returned to the convection furnace. After 900 seconds in the furnace, the temperature of the sphere is 240.5 °C. What is the convective heat transfer coefficient in the convection furnace? 5 O 7.8 W/(m² °C) 15.5 W/(m² °C)

I asked for problems 6 and 7 to be answered, but I did not get a properly structured answered as the example shows on problem number 1. Here is the link to the questions I already had answered, could you please rewrite the answer so its properly answered as the example shows (Problem 1)? https://www.bartleby.com/questions-and-answers/it-vivch-print-reading-for-industry-228-class-date-name-review-activity-112-for-each-local-note-or-c/cadc3f7b-2c2f-4471-842b-5a84bf505857
I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5. 1 pass 2 fail 3 fail 4 pass
Draw the the following views of the figure. Thank you.
