An airplane in a horizontal circle at a speed of 130.5556 m/s. If its wings are tilted 40 degress to teh horizontal, what is the radius of the circle in which the plane is flying? Assume that the required force is provided entirely by an "aerodynamic lift" that is perpendicular to the wing surface?

I have this equation that i used, its all that i have..but it has gravity in it..so i dont know if i did it right

tan angle = v^2 / g x R

r is radius
g is gravity
v is velocity
angle would be the 40
