To find the diameter of the sun, we need to use trigonometry.
The angular diameter of the sun is given to be 1920, and the distance of the sun from the Earth is 1.496×10¹¹ m.
To solve for the diameter of the sun, we can use the following equation:
Sun's angular diameter \* Distance to the sun from Earth = Diameter of the Sun
Plugging in the values given
1920*1.496x10(11)
