Once you have the radius, the formulas are rather simple to remember. Just as with the circumference of the circle, you will need to use pi (π). Generally, you can round this infinite number to 3.14 or 3.14159 (the accepted fraction is 22/7). Surface Area = 4πr2 Volume = 4/...

Use the known formulas for the sums of ( k ) and ( k^2 ): [\sum_{k=1}^{n} k = \frac{n(n+1)}{2}] [\sum_{k=1}^{n} k^2 = \frac{n(n+1)(2n+1)}{6}] Combine these results: [S = \frac{n(n+1)(2n+1)}{6} + \frac{n(n+1)}{2}] Factor out ( \fra...
Yet he was able to come out with stunning formulas such as this approximation for Pi: $latex \displaystyle\frac{1}{\pi} = \frac{2\sqrt{2}}{9801} \sum_{k=0}^\infty \frac{(4k)!(1103+26390k)}{(k!)^4 396^{4k}}$ Source: http://in.reuters.com/article/2013/07/25/ramanujan-...
