x/(pi(20^2))=(71)((0.023)/(20))(0.33)

解

\frac{x}{π ( 2 0 ^{2} )} = (71) (\frac{0.023}{20}) (0.33)

x = \frac{53889 π}{5000}

十進法表記

x = 33.85945 \dots

解答ステップ

\frac{x}{π ( 2 0 ^{2} )} = (71) (\frac{0.023}{20}) (0.33)

簡素化

(71) (\frac{0.023}{20}) (0.33) : \frac{53889}{2000000}

\frac{x}{π ( 2 0 ^{2} )} = \frac{53889}{2000000}

以下で両辺を乗じる:

π 2 0^{2}

x = \frac{53889 π}{5000}
