Answer:

36 years

Step-by-step explanation:

Given the equation of Kepler's third law as T² = a³, you want to know the period of an asteroid that has an orbital radius of 11 au.

Period

Solving the given equation for t, we find ...

T = a^(3/2) . . . . . . take the 1/2 power

Then for a=11, the period in years is ...

T = 11^(3/2) ≈ 36.48

The period of the asteroid is about 36 years.
