# Math Help - Equation arranging.

1. ## Equation arranging.

Another wierd question.
The following formula may be used to study planetary motion.

GmM/R^2=m4pi^2R/T^2. (Hope its not too confusing)

Make T the subject of the equation.
Thanks eveyone for the help.
AWSOM GUY

2. $\frac{GmM}{R^2}=\frac{m4\pi^2R}{T^2}$
$T^2=\frac{m4\pi^2R^3}{GmM}$
$T=\sqrt{\frac{m4\pi^2R^3}{GmM}}$
$T=2\pi\sqrt{\frac{mR^3}{GM}}$
