1. What were the steps you took to solve your problem? What mathematical concepts did you use and how did you use them?
To start of the problems, I found out the circumference of each sphere- the globe and the Earth. That amount would be the string length that fit perfectly around each shape. Then, since the problem asked if the string increased by a foot, I converted both of the amounts to feet and added one foot to each. Then I just moved backwards through the problem, and applied the new amounts to the equation π * d = c. The amount that came out of that equation was the new diameter. I divided it by two, and that gave me the radius which is what the question was asking for.
2. What were some questions you had when solving this problem? How did you answer them? or do you still have them? What are your conclusions from working on this task?
I got caught at one point when I got the first circumference because the two amounts were in different units. I didn't think to convert them, but once I got some guidance I was able to move on.
3. Why did you chose to do the problem you picked? Did you find one more challenging than the other? If so why was it more challenging? If not, was there something about the problem that stood out from the other? Please be as detailed as possible.
I chose to do this problem because I felt I had mastered it, and I wanted to display my knowledge. I found the other problem slightly more difficult because graphs have never been my strong point.
