Scientists collected evidence to form a valid theory about the formation and early development of the solar system include:
- Stars forming the depths of giant clouds of gas and dust.
- Young stars with disks of debris around them.
<h3>
What is Solar system?</h3>
This is referred to the gravitationally bound system of the Sun and the objects that orbit it.
It also comprises of the planets and their moons and objects such as asteroids and the evidence which shows that the formation of the solar system are the gas and dust which form the stars and debris found around them.

<u>Answer:</u> The cross-sectional area of the cylindrical rod is 
<u>Explanation:</u>
We are given a cylindrical rod whose cross-sectional area will be in the form of circle.
To calculate the area of circle, we use the equation:
where,
r = radius of the rod = 
(Conversion factor: 1 m = 1000 mm)
Putting values in above equation, we get:
Hence, the cross-sectional area of the cylindrical rod is
