There's not nearly enough information here to answer. (Among other things, what the heck is "shere" supposed to be?)
The general formula of an eigenvalue equation is Of = Ef. (Sorry, I can't do the normal mathematical notation here, but O is supposed to be an operator, and f is a function of some kind... E is, of course, the eigenvalue). If you know how to do differential equations, the rest is easy (assuming you actually know what O and f are). If you don't, you're not going to understand the answer anyway.
Volume of a sphere = 4/3*pi*radius3 in cubic units.
To calculate the surface area of a sphere use the formula - 4pr2 r being the radius of the sphere. and 'p' being pi 3.14...
calculate the volume using the formula: Vsphere = (4/3)*pi*r^3 then calculate density by Density = Mass/Volume
Answer,The surface area of earth is 510072000 Sq.km.And the formula of earth is,the earth is sphere.: The area of earth = Area of sphere" " = 4*pi*r2= 4*22/7*4057390.9= 510072000
The answer will depend on the figure. A circle or sphere, for example, has a different formula for whatever it is that you want to calculate.
Based on what? If you know the radius, you can use the formula for a sphere - which is a good approximation in the case of Earth and Moon.
Formula for calculating the area of sphere is : 4 * pi * r * r
The formula for the surface area of a sphere is: 4 pi r 2
Volume = 4/3(Pi)(r^3) Formula for volume of a sphere.
there would be no" lateral" surface to a sphere because it is round , only with a cube ,pyramid or rectangular object would you have lateral surface,although it is still possible to determine the surface area and volume of a sphere, the formula to calculate the area of a sphere is 4x pie x radius squared, to calculate the volume the formula is 4x pie x radius cubed divided by 3, to calculate a hemisphere you would divide the answer in half.
You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2
Surface area of a sphere = 4πr2
