who to calculate the angular diameters( in radians) of the sun and the moon, as seen on the earth?

Question

When Elipses happen on the earth because of an amazing coincidence, how to calculate the angular diameters in radians of the sun and the moon, as seen on earth.

Answer 1

A very basic way of doing this is by holding your outstretched hand at arms length in front of you - hiding the object to be measured (move your hand the appropriate number of times to cover the object). Each hand movement should cover approximately 10°. Then there is 57.3° to a radian. From there is is a simple deduction.
