Question

the sun's angular diameter is measured to be 1920 .the distance of the sun from the earth is 1.496 ×10^11 m. what is the diameter of the sun?
​

Answer 1

Answer:

That's 40 degrees, 11 minutes, 15 seconds, a minute being 1/60th of a degree and a second being 1/60th of a minute. (Thank you Babylonians.)

So we're to understand 1920" as

Answer 2

Answer:

1.39 × 10^9 m

Explanation:

Here its given that,

Angular diameter of sun = 1920

Then, we must have to convert this diameter into radians in order to solve this problem.

Angular Diameter of Sun, means the angle subtended by two diametrically opposite points at given point on Earth.

Sun's angular diameter is 1920".
