If i have a volleyball and draw a circle around the centre, then draw a line between the top of the ball and the centre and measure the two line I find that the ratio circumference of the circle to diameter of the circles is 4, thus implying that in this case pi is 4, however if I drew a circle of a different size I would get a different ratio.
Could anyone tell me if the value of pi changes in curved space, or if it is the equations that need to be updated?
Thanks in advance for your help.
