Surface area of a sphere with radius r = 4(pi)r2
There is NO equation for the area of a sphere Assuming you mean surface area, the surface area of a sphere of radius r is 4πr^2.
the volume of a sphere is 4/3 times pi times the radius of the sphere cubed. V=4/3 Pie r3
One might find the mathematical equation for the surface area of a sphere in a mathematics textbook. One might also find the equation at online math study groups.

That depends what you know about the sphere. For example, if you know the diameter, just divide it by 2 to get the radius.
4 pi r 2
measure the radius of the sphere and apply the appropriate volume equation: V= (4/3) x (pi) x r3
to find the volume of a sphere the equation is v= 4 over 3 x pie x the radius cubed
There is no equation for the "scale factor" of a sphere. If I assume you to mean how the volume increases with radius then you would use the volume equation for a sphere and calculate volume based on corresponding radii. You could then divide the resultant volumes to give a percentage or factor of how much larger or small one sphere is than another. You'll see that a small change in radius causes a large change in volume due to the volume being a cubic factor of the radius.
The equation for circumference is C=2(pi)(r) where C is the circumference and r is the radius. You can find the radius by plugging in the circumference into this equation and solving the equation.
The equation is: (4/3)Pie r3The worded equation is: Four thirds Pie multiplied by the radius cubed.answer 2 Archimedes might have immersed the sphere in a liquid, and measured the volume that was displaced.
