355/113 is a better approximation.

In fact, if you assume the earth is exactly 6371 Km in radius (says Google... and a perfect sphere) using 355/113 would put your measurement of the earth off by only 3.4 METERS from the true value.

355/113 is the best simple approximation for everyday use.

the suns total volume would be off by 10% of an earth volume
