Triple the Area of a Circle

[Acorn]

This is possibly the last Circle Challenge as the math / maths might be getting in the way of what are supported to be accurate design approaches to laying out and scaling circles using the power of Xara.

Can you accurately, without calculation, construct a circle from another so the new circle's area is three times larger?



At present I have two construction methods but both involve some in-between scaffolding.

Good thinking,
