Calculations at a spherical segment or zone of a hemisphere. Our online calculators, converters, randomizers, and content are provided "as is", free of charge, and without any warranty or guarantee. r = radius Copy. Enter the radius, Now you know, that fish tank has the volume. The user of the calculator will also be provided with a running total that will accumulate as new dimensions are added to the volume calculator. circumference = 2 * π * r, so r = circumference / (2 * π). Clear all. In mathematics, a sphere is defined as the set of points in a three-dimensional space that are all at the same distance \(r\) (radius of the sphere) from a given point (center of the sphere).  2020/10/08 08:09 Male / 20 years old level / High-school/ University/ Grad student / Very /,  2019/11/29 12:05 Male / Under 20 years old / Self-employed people / Very /,  2019/04/09 15:43 Male / Under 20 years old / Elementary school/ Junior high-school student / Not at All /,  2019/02/08 08:36 Male / Under 20 years old / Elementary school/ Junior high-school student / Very /,  2018/10/16 23:21 Male / Under 20 years old / Elementary school/ Junior high-school student / Useful /,  2018/01/24 15:07 Male / Under 20 years old / Elementary school/ Junior high-school student / Useful /,  2018/01/18 23:13 - / 60 years old level or over / A retired people / Very /,  2017/04/12 18:46 - / - / - / Very /,  2010/02/03 09:18 Female / 20 level / Self-employed people / Very /,  2009/10/21 11:52 - / 50 level / Others / Very /.

Enter the value of any known parameter in the fields of this online calculator and find the remaining unknown parameters. The unit of the resulting number is the cube of the length unit used for the radius/diameter. The formula for its volume equals: Usually, you don't know the radius - but you can measure the circumference of the sphere instead, e.g., using the string or rope. If you ever wondered what's the volume of the Earth, soccer ball or a helium balloon, our sphere volume calculator is here for you. Use this calculator to easily calculate the volume of a sphere, given its radius in any metric: mm, cm, meters, km, inches, feet, yards, miles, etc. Volume of a sphere Calculator . Just use the formula for the spherical cap volume with the parameters equal to each other: sphere radius = height of the cap = cap base radius. The mean radius is approximately 6.37 x 106 m. The volume is then: volume = (4/3) x π x (6370000 m)³ = 1,082,696,932,430,002,306,149 m³. \(\pi = 3.142\) The value of the radius is half of the sphere diameter. One example of the spherical dome is the fish tank, let's calculate how much water do we need to fill it: How to calculate it? See our full terms of service. The calotte is the curved part of the cap. Spherical Cap Calculator. amzn_assoc_tracking_id = "ezcalcme-20"; This all-in-one online Sphere Calculator performs calculations using the formulas which relate a sphere radius to its volume, surface area and circumference.
