Title: Re: What percent of earths radius is 20 kilometers? Post by: bolbol on Sep 7, 2023 To answer this question, you need to know the radius of Earth in kilometers.
According to some sources, the radius of Earth ranges from about 6,357 km (polar radius) to about 6,378 km (equatorial radius), depending on where you measure it. The volumetric mean radius, which is the average of all radii, is about 6,371 km. You can use this value as an approximation for your calculation. To find the percentage of Earth’s radius that is 20 kilometers, you need to divide 20 by the radius and multiply by 100. Using the mean radius of 6,371 km, you get: (20 / 6,371) x 100 = 0.314% This means that 20 kilometers is about 0.314% of Earth’s mean radius. |
