Ok, this is physics question that I keep getting wrong. Help please!

A 1.57-gram airplane is attached to a string with a length of 1.32 meters. The plane flies in a circle in which the string is declined at an angle (Theta) of 31.7 degrees below the horizontal. At what speed (in m/s) is the plane flying?
