Question

the radius of the sun is 695 500 km. what is its diameter written in scientific notation​

Answer 1

Given,

The radius of the sun = 695500 kilometres

To find,

The diameter of the sun in scientific notations.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

First of all we have to calculate the normal value of the diameter of the sun.

Diameter = Radius × 2

Diameter = 695500 × 2

Diameter = 1391000

Diameter in the scientific notation = 1391000 km = 1.391 × 10⁶ kilometres

Hence, the diameter of the sun is 1.391 × 10⁶ kilometres
