The formula for the surface area of a circle is _A_ = π_r_2, where _A_ is the area of the circle and _r_ is the radius of the circle. An Introduction to Pi In order to calculate the area of a circle you'll need to understand the concept of Pi. Pi, represented in math pr...
You probably think of a radius as a property of a circle in two dimensions or of a three-dimensional sphere. However, mathematicians also use the term to refer to certain distances in regular polygons. In more casual use, radius of a square may also refer to the radius of a circle asso...
How to Calculate the Volume of a Sphere The formula for the volume of a sphere is 4/3 ×πr3, where r is the sphere's radius. That's pretty straightforward, except in practice, it can be difficult to measure the radius. Even if you have a scaled 2D projection of th...
i am trying to calculate the electric field of a spherical charge distribution ρ=ρ[itex]_{0}[/itex]e[itex]^{-kr}[/itex], where r is the radial distance. i am a little bit embarressed,but i have to say that i am not comfortable with spherical coordinates in practical ...

To calculate the volume of a cylinder, one must know the height and radius (the distance between the edge of the circle and its centre point) of one of the flat ends. If the dimensions are given in cm, the volume is measured cubic cm (cm3). Though you can also measure the volume ...
When the radius is 12 meters, then how fast is the VOLUME changing? Note: Volume of a sphere = (4/3) ⋅ π ⋅ (radius)3 The rate of change of the VOLUME is ___ cubic meters per hour. (Enter your answer as a decimal number rounded to 2 places.)Follow...
