When do the angles of a triangle add up to more than 180 degrees?

[scooterscot]

No. Any negative curved surface, such as a hyperbolic surface. The surface is always with 3D .

din't read the question properly,

Bit of a trick question. It varies according to where you draw the circle. If you do it in the right place, you can have pi = exactly 3.

How can it? A perfect circle on a perfect sphere has an infinite amount of symmetries, why would it matter where the circle is placed?

The ratio is only pi if you measure both the diameter and circumference in a euclidean 2D plane in 3D space. Measured on the 2D surface of a sphere the ratio will always be less. For example, a circle around the equator has a circumference exactly twice it's diameter, as on the 2D surface of the sphere the diameter is exactly half of an identical circle through the poles.

Ich verstehe,

I was thinking of a circle not following the surface of the sphere. I.e. resting a hoop on the sphere. doh. Much like a radar would see the sphere despite no matter which way the target was observed by the transmitter.

Surely you mean Doritos? Pringles are round.

Only if you buy the supermarket own-brand ones.
