It is about 0.949 times Earth's radius.
Venus' radius = 0.95 of Earth's Venus' mass = 0.815 of Earth's
If you want an approximate answer, we can assume the Earth and the Moon to be spheres, then go google for their radii, and plug that in the formula for volume of a sphere,V=(4/3)*pi*(radius)^3. Volume of Earth about 1.08321 x 10^12 km^3 Volume of Moon about 2.1958 x 10^10 km^3 The purpose of my answer was to explain how to calculate the volume not of just earth and moon, but any celestial object that can be approximated to a sphere, provided you know the radius. ps- I know the question is to tell the volume, not how to calculate it, but I thought the latter way of approaching the question would be more helpful!
The Earth's radius is6 378.1kmSo that means that the earth is 1.88 (almost 2) times larger.
Speed of light = 186,282 miles per second.500 seconds at this speed = (500 x 186,282) = 93,141,000 miles
This is hard to calculate precisely, due to the fact that Earth's density increases towards the center. However, you make a simplified calculation, by assuming a uniform density. Just calculate the ratio of the volume (and therefore, of mass) of a sphere which has half the radius of the Earth, and calculate the gravitational attraction (once again, you only need a ratio, compared to the complete Earth) on that object.
Based on what? If you know the radius, you can use the formula for a sphere - which is a good approximation in the case of Earth and Moon.
if g=9.8m/s, G=6.7*10-11Nm2kg-2,calculate the mass of earth, if the radius of the earth is approximately 64m
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!
Eratosthenes (a greek) was the first person known to have accurately measured earth's radius. He did that about 250 BCE. The trick was to measure the length of the shadow cast by the library at Alexandria during the summer solstice, and knowing the distance between Alexandria and Cyene--a city on the Tropic of Cancer. A bit of trigonometry, and earth's radius falls right out.
It is about 0.949 times Earth's radius.
If you are a believer, then God did but if you are not, then nobody did. The radius of the earth existed and therefore ots radius did before there was any form of life on earth to invent it.
Venus' radius = 0.95 of Earth's Venus' mass = 0.815 of Earth's
Europa: 1561 km radius Earth: 6371 km radius The diameter is twice the radius.

Mercury's radius is 0.3825 that of Earth Jupiter's radius is 11.209 that of Earth So: (0.3825/11.209)*100 = 3.41 percent.
Distance from Earth to Moon is approximately 60.34 times larger than radius of Earth.
