If the radius of the sun is 7.001×105 km, what is the average density of the sun in units of grams per cubic centimeter? the volume of a sphere is (4/3)π r3.

Average density of Sun is 1.3927 .

Given:

Radius of Sun = 7.001 × km = 7.001 × cm

Mass of Sun = 2 × kg = 2 × g

To find:

Average density of Sun = ?

Formula used:

Density of Sun =

Solution:

Density of Sun is given by,

Density of Sun =

Volume of Sun =

Volume of Sun =

Volume of Sun = 1.436 ×

Density of Sun =

Density of Sun = 1.3927

Thus, Average density of Sun is 1.3927 .
