Not sure about the eartn, but earth has a mean radius of 6370 km.
Mars is. Mars has a mean radius of 3397km while our moons mean radius is 1737km.
The radius of Earth is 6,378.1 kilometers, or 3,959 miles. The radius is the distance from the Earth's center to its surface.
No. Rhea has a mean radius of 764 km. Earth's moon has a radius of 1737 km.
Highest mountain above sea level is Everest. Earth mean radius is 720.852 times it's height. Tallest mountain from it's base is Kea. Earth's mean radius is 637.81 times greater that Kea's height from it's base.
That depends what you mean by "size". Diameter: 0.38 times the diameter of Earth. Radius: same number, since the radius is half the diameter. Volume: the ratio of the diameters cubed. Mass: 0.055 times Earth's mass.
It is about 0.949 times Earth's radius.
Earth's mean (average) radius is about 6371 kilometers, so yes.
Earth's mean (average) radius is about 6371 kilometers, so yes.
Venus is smaller but not by much. The Earth has an mean radius of 6,371 km whereas Venus is 6,052 km (0.950) that of Earth)
The ratio of the surface areas is (earth's radius/moon's radius)^2 where the radii are in the same units.This gives the answer as 13.40, approx.And, incidentally, the word is radius, not raduis!
The mean diameter of Earth is 12,742 kilometers or 7917.5 miles.More specifically, if we quote the accurate values for the radius, it changes depending on where you measure it.Mean radius 6,371.0 km = 3958.8 milesEquatorial radius 6,378.1 km = 3963.2 milesPolar radius 6,356.8 km = 3949.9 miles
