Question

A scientist wants to estimate the volume of Earth and uses a sphere as a model for the planet.
According to NASA, Earth’s diameter is 12,756 km. The volume of a sphere is four-thirds of the
product of Pi (π) and the radius cubed. Using 3.14 for π and that the radius of a sphere is equal
to two times its diameter, estimate the volume of Earth.

Answer 1

Thus the radius is 6,378!
Now just put it in the equation = 4/3 * pi * 6,378 * 6,378* 6,378!
And then you are done! :)
I hope this helped! :)

Answer 2

You are the best O thank you
