Verified answer

a circle with infinity radius is actually a straight line because if u draw normals to a straight line they meet at infinity that is the center of the straight line is actually located at infinity. (as normals drawn to an arc meet at the center)

A circle with a radius of infinity is a straight line !!

x^2 + y^2 = ∞

a circle with a radius +∞ would look like a longitude or latitude line of universe.

What is the form of the circle?

Circular.

it will be a plane extending in all directions. the arc of any part of the circle can be considered to be a straight line.

∞ is NOT a number, and cannot be treated as such. There is no such thing as a circle with "radius +∞".

Big

i have never seen this question before...beautiful one...i think it is a plane

elliptical
