anonymous one year ago PLEASEEE HELP!!!! The formula to find the period of orbit of a satellite around a planet is T2=(4π2GM)r3 where r is the orbit’s mean radius, M is the mass of the planet, and G is the universal gravitational constant. If you are given all the values except r, how do you rewrite the formula to solve for r?

1. anonymous

you want to isolate r

2. IrishBoy123

this is the correct equation $$\large T^2=\frac{4π^2}{GM}r^3$$

3. anonymous

yes that's the one

4. anonymous

T2=(4π2GM)r3 $( \frac{ 1 }{ 4\pi2gm})T2= r^3$ $r=\sqrt[3]{\frac{ t2}{ 4\pi2gm }}$

5. anonymous

deeez that's not one of my options... hold up... im new ill try to uploaod them for you

7. IrishBoy123

what happens if you multiply each side of the equation by GM? you can draw it if you have problems entering equations

8. anonymous

it gets cancelled out in the denominator and goes to the opposite side of the equation

@Deeezzzz

10. anonymous

thank you

11. IrishBoy123

and then divide both sides by $$4 \pi^2$$ ??
