The area of a sphere is equal to its circumference times its diameter.
There are a variety of ways to work out this formula, most of them involving calculus.
(See the links for the volume of a sphere).
Yes. Second contribution: Surface area of sphere = XXXVI = 36 square inches. When all the working out is done, which the previous contributor has failed to do, the answer is: Volume of the sphere = 20.311 cubic inches correct to three decimal places. This was achieved by rearranging the formula (4*pi*r2) for finding the surface area of the sphere in order to find its radius. The radius was then used in the formula (4/3*pi*r3) for finding the volume of the sphere.
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
Approximately 546.1 ft2. To show work, The volume is 4/3 piR^3 and surface area is 4 pi R^2 Solve for R fromVolume; 1200 = 4/3 pi R^3 R = 6.58 A = 546
That is the definition of the area of a rectangle. It does not work for any other shape.
you need to work backward for find the radius from the volume then work forward and find the surface area. The volume is 36 Pi cm3 The formula for the volume inside of a sphere is 4/3 Pi x radius3 so 36xPi=4/3 Pi x radius3 So 108/4=the radius3 so 27 is the radius cubed hence 3 is the radius. This tells us the surface area is 4xPix32 =36Pi cm squared. So in the surface area is also 36 but the units are square cm.
Tricky. You need to flatten out the surface to work it out. Depends on the shape - if it's like a hemisphere then you can use the properties of a sphere - volume = 4/3 Pi R3 and surface area = 4 Pi R2 so if your dome is like half a sphere then its surface area = 2 Pi R2 and you can measure the radius R so can work it out!
to find the volume of a sphere the equation is v= 4 over 3 x pie x the radius cubed

Formula for surface of sphere is 4 X pi X radius squared.4 x 4squared = 64 pie = 201.0622498so your answer is64 pie or 201.0622498(Either would work)
You work both out from measurements of the shape and the relevant formulae.
To work out the area of a sphere, you have to know its radius. Once you know that: -- 'square' the radius (multiply radius times radius) -- multiply that result by 12.5664 The result is near the area of the sphere.
To work out the area of a composite shape, you will have to divide it into smaller figures.

A quadrilateral does not have a surface area because it is not a voluminous figure.
take 1 face and times the base by height and the times it by the number of faces b * h = area of 1 face area of 1 face * number of faces = surface area note all faces must be the same! Hope i HELPED :D
