Answer:
sun is bigger than earth is 13.9 cm
Explanation:
given data
radius of sun = 700,000 km
radius of earth = 6500 km
to find out
how big is the sun
solution
we know here
scale 1 to 10 billion is
scale = [tex]\frac{1}{10*10^9}[/tex]
so here
we know that scaled diameter = actual diameter × scale .................1
so for earth
scaled diameter of earth = 2 × 6500 × [tex]\frac{1}{10*10^9}[/tex]
scaled diameter of earth = 1.3 × [tex]10^{-6}[/tex]
and
scaled diameter of sun = 2 × 700,000 × [tex]\frac{1}{10*10^9}[/tex]
scaled diameter of sun = 1.4 × [tex]10^{-4}[/tex]
so
sun is bigger than earth is 1.4 × [tex]10^{-4}[/tex] - 1.3 × [tex]10^{-6}[/tex]
sun is bigger than earth is 0.000139 = 13.9 cm
