Löse

h r^{2} = \frac{200}{π} : r = \frac{10 2}{πh}, r = - \frac{10 2}{πh}; h \neq = 0

r = \frac{10 2}{πh}, r = - \frac{10 2}{πh}; h \neq = 0

\frac{3 x}{5} = \frac{4 ( 15 - x )}{x}

\frac{x}{x + 1} = x - 1

\frac{( x ^{2} + x )}{x - 1} = 6

x^{- 4} - 13 x^{- 2} + 36 = 0

\frac{1}{x} = \frac{3}{5 x}
