From my homework, I have to to find the area of circle. One of my tasks is to trace a cylinder end down and then on graph paper trace the end of each. I did already that, but now I am having troulb converting the number of squares to square centimeters. Here are my numbers of squares:
object 1: 472
object 2: 796
object 3: 104
object 4: 313
The graph paper than I am using has 5 lines per centimeter, it will take 25 little squares to equal 1 cm^2.
