Hello. Please graph period vs. orbital radius. Be sure to title axis and find a nice scale. You may use Excel or just hand draw it. But, when graphing, before you put the points, square the orbital period, and cube the radius. This is to demonstrate a cool law. It should fit a linear relationship. Thank you :)

Orbital Radius (Mm)	Period (mins)	Speed(m/s)
8Mm	120 mins	1.0803x10^-8 m/s
8.4Mm	127 mins	1.0543x10^-8 m/s
8.8Mm	138 mins	1.0301x10^-8 m/s
9.2Mm	148 mins	1.0074x10^-8 m/s
9.6Mm	157 mins	9.8625x10^-9 m/s
10Mm	169 mins	9.6891x10^-9 m/s
10.4Mm	179 mins	9.4756x10^-9 m/s
10.8Mm	188 mins	9.3858x10^-9m/s
