minus-squareSkyezOpen@lemmy.worldlinkfedilinkarrow-up2·5 months agoRight, so you’d need 3.14 strings of length D to cover the circle, D wouldn’t wrap around it itself.

minus-squareSkyezOpen@lemmy.worldlinkfedilinkarrow-up3·5 months agoYeah that’s what I gathered, but it’s backwards. C = Pi D means you need pi strings, not that it’ll cover the circle pi times.
minus-squareAlteon@lemmy.worldlinkfedilinkarrow-up4·5 months agoAhhhh. I see what your saying. It’s fixed. Yeah. Did not mean to intend that it wraps fully around the circle pi times. Good catch.
