What is the orbital velocity of the Earth around the Sun, assuming the Earth takes a perfectly circular orbit around the Sun?

What would be the centripetal acceleration of the Earth around the Sun?

(I have no clue :()
From my textbook I found out that Earth has a mass of 5.97x10^24 and radius of 6.38x10^6m and distance from sun is 1.5x10^11m; the sun has a mass of 1.99x10^30 and radius of 6.96x10^8

I don't know which equation to use
