Question

The angular diameter of the sun as observed from the earth is 32’. Calculate the diameter of the sun if its distance from the earth is 1A.U.
with explanation..​

Answer 1

answer

$1.4 \times 10 {}^{9} m$

Explanation:

angular diameter(α) =32'

but as α=32× π/60×180

=0.009 rad

distance from the earth(I) 1A. U. = 1.5×10 ^11 m

then, the diameter of the sun D= lθ

= 1.5×10^11×0.009

=1.4×10^9 m

Answer 2

Explanation:

The distance from the Earth to the sun is called an astronomical unit, or AU, which is used to measure

distances throughout the solar system .......However,

to measure longer distances, astronomers use light

years, or the distance that light travels in a single
