Question

Calculate the mass of earth

earth assum
assuming
that it i a
6.67x106m.
Sphere with radius​

Answer 1

`m=6.85* 10^(24)\ kg`

Step-by-step explanation:

The radius of Earth is
`6.67* 10^6\ m`

The density of an object is given by :

`d=(m)/(V)`

The density of Erth is, d = 5515 kg/m³

Where

m is the mass of the Earth

So,

`m=d* V\\\\m=(4)/(3)\pi r^3* d`

Put all the values,

`m=(4)/(3)\pi * (6.67* 10^6)^3* 5515 \\\\m=6.85* 10^(24)\ kg`

So, the mass of the Earth is equal to
`6.85* 10^(24)\ kg`.
