You could use the fitBounds method of GMSCameraUpdate, passing in a GMSCoordinateBounds which is calculated from the edges of your circle.

Based on this answer, it looks like you could use MKCoordinateRegionMakeWithDistance to convert your centre (lat/lon) plus radius (metres) into a MKCoordinateRegion, which will convert the metres into a span in degrees, therefore allowing you to calculate the coordinates in degrees which you'd use to create the GMSCoordinateBounds.
