Double the Area of a Circle

...but as there were no "calculations" you get a pass.

That is a good refinement of Keith's approach

Keith's memory deserves the all the credit - I just looked at what he said and thought [like you] thats more complicated than it need be; I took the maths on trust

i have a wheeze / trick / gimmick that I think improves even on this.

well I guess if you have the starting circle aligned to the square all you have to do it drag it, or a clone, out to the corners - could it be much simpler than that?

or are we talking about a different approach ?

Much simpler ... Show grid ... Snap to grid.

oh please I knoweth not the math and the signs he giveth

edit - and besides, that's a calculation and therefore going off at a tangent [but I do see what you mean, I think - we have the same square root of 2 ratio, inverted, that acorn was refering to... ? I can handle ratios; but numbers, like letters, are apt to confuse me when they get serious as someone once said ]

I wasn't doing the actual calculation, just hinting at the solution.

[handrawn]

twas a good hint I just don't like maths

with regard to the snap points - how are you defining which ones to use?

[Acorn]

Much simpler ... Show grid ... Snap to grid.

Keith, obviously stimulating the creative juices.

Without a grid, using Snap to Shapes:

ah another way of looking at the symmetry

[Acorn]

My approach was to clone the circle and with the QuickShape tool change the clone to a square (create polygons, 4 sides).
Shift-dag a corner until the square is the same width/height as the original circle.
Final QuickShape tool change square back to a circle (Create ellipses).

My method clones a shape and morphs it into the final circle without creating additional scaffolding.



Keith's refined method is probably simpler to explain and understand so has to be the current winner.

changing the circle to square and back is not something I'd thought of doing, so something for me to take away

I'm a bit late to the challenge but have posted a similar method as above I used.
