Answer:
Step-by-step explanation:
There is too much of this that we don't know. It's going to make if very hard to answer. If I guess, I think the mods will wipe it out because I am guessing.
1. What's the scale? How big is the side of the square? Using a micrometer, when the question first comes off, from what we can see, the side of each square is roughly 0.44 cm.
2. We are are certain what you did next. You had to have measured the diameter, and calculated the radius. That's a fair enough procedure.
3. Is the number of squares = to the radius or the diameter?( sometimes it looks like the diameter and sometimes the radius, and the odd time neither one. Why not just scan the whole sheet and put it up.
