Given that The radius of the earth's orbit around the sun (assumed to be circular) is 1.50 \\times 10^{8}\\; {\

m km}, and the earth travels around this orbit in 365 days, what is the orbital velosity of the earth?

I tried to do the following

x = 1/2 vt

1.5x10^11 meters = (.5)(v)(31536000 seconds)

1.5x10^11 meters = 1.5768x10^7 seconds * v

9512.94 meters/second = velocity

but this isn't the right answer, what am I doing wrong?
