b) The x-component of this wind can be calculated using: Wx = 6cos(45) Wx = 4.24 km/hr This is greater than the opposing flow of the river from the east. Therefore, should row in a direction due south west to counter the wind's force as well as move towards his destination.
you can find the radius as:
