Please help. Thank you.

Answer: a=4.99 m/s²
The question refers to centripetal acceleration. It acts perpendicular to circular trajectory so it does not affect circular speed (thus "constant speed" in the text), it only changes the direction of the vector of speed.
a = v² / r
a = 6670² / 8.92x10⁶ = 4.99 m/s²
