The sun subtends an angle of 0.00928 rad when viewed from the surface of the earth, and its distance from earth is 1.5 × 1011 m. what is the diameter of the sun?

Answer 1

An angle of 0.00928 radians (on a circle) has
a length of 0.00928 of the circle's radius.

                  (0.00928) x (1.5 x 10¹¹)

              =      1.392 x 10⁹  meters
