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.
The sun is a sphere with an estimated mass of 2.00×1030 kg.
What exactly is the conversion process for this?
Raising a number in scientific notation to a power is easy:
(5 x 105)² = (5)² x (105)² = 5 x 5 x 105 x 105 = 25 x 10(5 × 2) = 25 x 1010 = 2.5 x 101¹1
Keeping this in mind, what is the volume of the sun in km³? The radius of the sun is about 7 x 105 km, and the volume of a sphere is 4/3 x Pi x R³. (Use 3.14 for Pi, and enter your answer with two decimal places).

What is the average density of the Sun? Density = mass / volume. The mass of the sun is 2.0x10³0 kg.
