by how much will the Earth radius increase?
10 points for the first correct answer
(you should be a bit suprised.. as how much it will increase by because of one meter..)

Thank you for all for your answers. As promised 10 points to the first one :-)
is this not amazing to think just by increasing 1m earth would be so much bigger?? (and heavier??)

The circumference of a sphere is two pi times the radius. (The Earth is actually an oblate spheroid, but the math works out the same as for a sphere.) Thus, if you increase the circumference by one meter, the radius must increase by one meter divided by two pi, or 159 millimeters.
Even though 159 millimeters doesn't seem like much, it would take about 447,000,000,000,000 metric tons of rock to increase the Earth's radius by 159 millimeters.

If we assume that the circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers).
That is 40,075,160 meters then the radius will be 6,378,159.809m
If we add a meter .....
That is 40,075,161 meters then the radius will be 6,378,159.968m
0.159 meters, about 16 cm
I think....

C=2Pi*R
dC/dR=2Pi
for one meter
dC=1
1/dR=2Pi
dR=1/2Pi
dR=0.159meters
The cute bit about this is it is independant of the size now. I mean if you did this for jupiter, a tennis ball, the sun the change would be the same.

C = 2*Pi*r
C + 1 = (2*Pi*r) + 1
r = [(C + 1)/(2*Pi)] - (1 / 2*Pi)
Now just find the circumference of the sun, and plug it into this equation.

r=c/2pi
new-r=(c+1)/2pi
so
new-r - r =
1/2pi [c+1-c]
= 1/(2pi) meters
