Question

Approximate the volume of the sphere.

6 x 104 km
Use 3.14 for at
and round the first factor in scientific notation to the nearest tenth.
Enter the correct answer in the boxes.

Answer 1

The formula for the volume (V) of a sphere is,

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

Given

`\begin{gathered} \pi=3.14 \\ r=6*10^4 \end{gathered}`

Therefore,

`V=(4)/(3)*3.14*(6*10^4)^3=9.0432*10^(14)\approx9.0*10^(14)km^3`

Hence, the answer is

`\begin{equation*} 9.0*10^(14)km^3 \end{equation*}`
