The great galaxy in Andromeda has an angular diameter along its long axis of about 5 degree. Its distance is about 2.2 millons light years. What is its linear diameter.

    Convert 5 degrees to radians (about 0.09) and multiply that by the distance from Earth. That will give you the diameter.

    It's a big one, like our Milky Way.
