LOL. The kid was right in the first answer. 40,000,000 / 3.14159265359 = 12,732395.45 METERS and 40,000,010 / 3.14159265359 = 12,732398.63. The difference in diameter (3.18m) / 2 = 1.59meters above the surface of the earth.Ray Taffhttps://www.blogger.com/profile/05800870620437423057noreply@blogger.comtag:blogger.com,1999:blog-3802979373213475425.post-35595189941136131622015-01-23T03:22:56.592+05:302015-01-23T03:22:56.592+05:30JyRKS, I think your decimal is in the wrong place....JyRKS, I think your decimal is in the wrong place. 10 meters is 1/100th of a kilometer, not 1/1000th.

Isn't C ...Should be fairly simple calculation. Isn't C = pi x D ? 40,000,000 meters is a diameter of 12,732,395.447 meters and 40,000,010 meters diameter would be a diameter 12,732,398.630 meters. The difference (3.2m) divided by 2 would be 1.6m. The kid who answered first looks to be correct.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3802979373213475425.post-38719657139845493052015-01-16T17:47:22.701+05:302015-01-16T17:47:22.701+05:30This comment has been removed by the author.JyRKShttps://www.blogger.com/profile/17075621615076889389noreply@blogger.comtag:blogger.com,1999:blog-3802979373213475425.post-819986955094174902015-01-13T01:41:40.665+05:302015-01-13T01:41:40.665+05:30Not even a flea...
