My DD is constructing a mandala which needs to have 120 individual (equal-sized) circles within a 3 metre diameter circle. I have found on the net an illustration of an arrangement of the circles that fits, but it does not say what size these small circles need to be.
Any maths wizards out there!!??
Sorry to tax your brains on this lovely sunny day.
Have any of you got all electric cars? Pros and cons please.
