簡約 4/3 pi(1.95)^3

解

簡約

\frac{4}{3} π (1.95)^{3}

31.05935 \dots

解答ステップ

\frac{4}{3} π 1.9 5^{3}

分数を乗じる:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{4 π 1.9 5 ^{3}}{3}

4 π 1.9 5^{3} = 29.6595 π

= \frac{29.6595 π}{3}

数を乗じる:

29.6595 \cdot 3.14159 \dots = 93.17806 \dots

= \frac{93.17806 \dots}{3}

数を割る:

\frac{93.17806 \dots}{3} = 31.05935 \dots

= 31.05935 \dots
