Theoretically it is said that, tangent touches to a single point on a circle. But If my circle is very big, and large enough, then i think, it should not be a just single point where my tangent is touching, though is will be a very small portion depending on how large is the circle.(adsbygoogle = window.adsbygoogle || []).push({});

If i have a perfect sphere of size of earth, then a perfectly flat surface of size of football field will completely be touching on to the earth's surface, and is not just at one point!

So, my question is, how big should be the radius of a circle, to perfectly allow 1 meter of area of a tangent touching perfectly on it?
