Question 144808
Kepler's third law of planetary motion is:
{{{T^2 = R^3}}} where: T = time of orbital period (years) and R= the average orbital radius (semi-major axis).
You want to solve for T for the planet Venus and you are give that R = 0.723 AU.
{{{T^2 = R^3}}} Take the square root of both sides.
{{{T = R^(3/2)}}} Substitute R = 0.723
{{{T = (0.723)^(3/2)}}} Use your calculator to get:
{{{T = 0.615}}}Years.
