Answer 1

I`m afraid the answer is not corret, how ever, your functions sound reasonable.
The problem should be the steps of calculation. According to your derivation of the distance between earth and moon :
(R+h)=[(g*R^2*T^2)/(4*pi^2)]^(1/3)
T^2 should be substituted as (30*24*36000)^2, instead of 30*24*36000, where the square (^2) is forgotten.
Please try again by using 30*24*36000)^2, you may probablely get the right answer.
Good luck
