In problems $4$ through $6,$ give the mathematical equations computed by the C$++$

statements. Assume that the following symbolic constants have been defined, where

the units of $G$ are $\frac{m^3}{kg**s^2}$ :

const double $\frac{?}{PI}=$acos$(-1\mathrm{.}0)$;

const double $G=6\mathrm{.}67259e-11$;

Centripetal acceleration:

centripetal $=4*\frac{*}{P}$I $*\frac{*}{P}$I $**\frac{r}{T**T}$;

Potential energy:

potential$\_$energy $=-G^{***}{M}_E^{**}\frac{m}{r}$;

Change in potential energy:

change $=G^{**}{M}_E^{**}{m}^{**}(\frac{1}{R_E}-\frac{1}{R_E+h})$;
