If you approximate the Earth as an ideal sphere (it is, in fact, a geoid) and you know the volume, you can calculate its radius. The numbers will be big, though! The volume V of Earth is: 1,083,206,916,846 km³. Apply the inverse formula for the volume of a sphere to find the radius: r = ³√[3 × V / (4 × π)] = 6371 km.

Spherical cap volume calculation. The spherical cap, also called the spherical dome, is a portion of a sphere cut off by a plane. The formula behind its volume is: volume = ((π × h²) / 3) × (3r - h) or: volume = (1/6) × π × h × (3a² + h²) where the radius of the sphere is r, the height of the cap (the blue one) is h, and a is the ...

The volume of a sphere is 4/3 x π x (diameter / 2)3, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4/3 x π x radius3. Visual on the figure below: Since in most practical situations you know the diameter (via measurement or from a plan/schematic), the first formula is usually most useful, but it's easy t...
Usually the hardest part is measuring or estimating the diameter of the sphere. Special tools exist for smaller parts like balls in ball-bearings, but it gets more complicated if the size is large. Knowing that the diameter is the largest internal measurement you can take should help. Once you have the measurement, to find the volume use the formul...
Only a single measurement needs to be known in order to compute the volume of a sphere and that is its diameter. For example, if the diameter is known to be 20 feet, then calculate the volume by using the first formula above to get 4/3 x 3.14159 x (20/2)3 = 4.1866 x 1000 = 4188.79 ft3(cubic feet). Alternatively, if the radius is given, multiply it ...
Jun 17, 2024 · The notation is as follows: r - radius of a sphere, V - volume of a sphere (sphere calc: find V), A - area of a sphere (sphere calc: find A), d - diameter of a sphere (sphere calc: find d), A / V - surface-to-volume ratio of a sphere. A sphere is a set of points in three-dimensional space at the same distance from a given point, called the ...

A: If you have the diameter, divide it by 2 to get the radius. Then you can use the radius to find the surface area or volume. Q: How do I calculate the surface area if I only have the volume? A: First, find the radius from the volume using ( r = \sqrt[3]{\frac{3V}{4\pi}} ). Once you have the radius, use the surface area formula ( 4 \pi r^2 ).

Basic definition and general information about the Sphere. A sphere is a three-dimensional object that is perfectly round and symmetrical, with all points on its surface equidistant from its center point. The following formula is used to calculate the volume of a sphere: Volume = 4/3 π * Radius 3; Where π is the constant (3.141592654)
