      1. This is a circle with a radius of 6400 km. Yellowknife is indicated to be at 62.45 degrees north and Crowsnest Pass at longitude 49.63 degrees north.

      2. This is one possible method for determining the distance.

         

        a = ?, r = 6400 km, θ = 62.45° − 49.63° = 12.82°

        To use the formula a = rθ, θ must be in radians.
