Asphereis a solid with all its points the same distance from the center. The distance is known as the radius of the sphere. The maximum straight distance through the center of a sphere is known as the diameter of the sphere. The diameter is twice the radius. ...
Volume of a sphere formulaGiven the radius, the volume can be found by using the following formula: V = (4/3)pir3 = (4/3)πr3 pi or π is a special mathematical constant, and it is approximately equal to 22/7 or 3.14. If r or the radius of the sphere is known, the volume ...

Determining the cell volume also enables the sphericity of each cell to be assessed. By comparing the measured cell volumes to the volume of spheres with radius r=A/π, where A is the measured surface coverage area of the cells, we found that most cells were approximately spherical (inset ...
2The volume, V, of a sphere of radius r is given by $$ V = \fra c { 4 } { 3 } \pi r ^ { 3 } $$.The radius, rcm, of a sphere is increasing at the rate of 0.5$$ c m s ^ { - 1 } $$ e. Find, in terms of t, the rate of change of the volume of t...
Multiplying the constants in this expression results in 4/3. What is the radius of a sphere? The sphere is a three-dimensional figure with a fixed point called the center. The radius of the sphere is the distance from the center of the sphere to any point on the sphere....
