This is my very first video. In the first two videos, I didn't include the voice over. From the third video I have included vocal explanation also. Thank you all for the suggestions...

Great visuals. Look forward to the voice.
Also, solved without trig by using algebra and right triangle side ratios, 1, 2, sq. root of 3.

Thank you 😍
And what you did is also a nice approach to solve...

I'm rather pleased with this one. I worked it out in my head in under half a minute, just by imagining a little extra construction.
Spoiler alert.
I mentally construct a vertical line segment from the centre to the point of tangency between the chord and the inner circle. That forms a 30° triangle, whose hypotenuse and shorter leg have the ratio of 2:1 in length, meaning that the inner circle must have half the radius of the outer one, and that the inner circle must have a quarter of the area of the outer one. The inner circle's area is therefore 4π square units, and so its radius is 2 units. By extension, the outer circle's radius must be 4. The total perimeter is therefore 2π ∙ (2 + 4) = 12π units, or about 37.7 units. The decimal approximation was not worked out mentally, but the rest was.

[@problemanalysis99]

Yeah correct. That's a good one 🤗
