Archimedes solved this in his famous book <em>Sphere and Cylinder</em> in 225 BC. The result is reportedly on his tombstone.
The ratio of the volume of the radius r sphere to the cylinder radius r, height 2r is
The same ratio is the ratio of the surface area of the sphere to that of the cylinder (including the ends).

Step-by-step explanation:

The sum of ( x + ) + ( x - ) is x +
To add or subtract 2 fractions, they must have same denominators, if they not do that
∵ ( x + ) + ( x - )
- Let us start with adding the like terms
∴ ( x + ) + ( x - ) = (
∵ ( x + x ) have same denominators, then we can add them
∴ ( x + x ) = x
∵ ( - ) do not have the same denominators, then we must find
LCM of 8 and 4
- The LCM of 8 and 4 is 8 because 8 is the first common multiple
of 8 and 4
∵ LCM of 8 and 4 is 8
- Divide 8 by the denominator 4
∵ 8 ÷ 4 = 2
- Multiply the numerator of the fraction by 2
∴
∴ ( - ) = ( - ) =
∴ ( x + ) + ( x - ) = x +
