the radius would be appr. 3960 miles

so the volume would be (4/3)π(3960)^2 cubic miles

To calculate the volume of Earth, we need to use the formula for the volume of a sphere. The formula is:

V = (4/3) * π * r^3

Where:
V = Volume
π = Pi (approximately 3.14159)
r = Radius of the sphere

Given that the diameter of Earth is 7920 miles, we can calculate the radius by dividing the diameter by 2:
r = 7920 miles / 2 = 3960 miles

Now we can substitute the value of the radius into the equation to find the volume:
V = (4/3) * π * (3960 miles)^3

Calculating this equation will give us the volume of Earth.
