簡約 4/3 pi(1.5)^3

解

簡約

\frac{4}{3} π (1.5)^{3}

14.13716 \dots

解答ステップ

\frac{4}{3} π 1. 5^{3}

分数を乗じる:

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

= \frac{4 π 1. 5 ^{3}}{3}

4 π 1. 5^{3} = 13.5 π

= \frac{13.5 π}{3}

数を乗じる:

13.5 \cdot 3.14159 \dots = 42.41150 \dots

= \frac{42.41150 \dots}{3}

数を割る:

\frac{42.41150 \dots}{3} = 14.13716 \dots

= 14.13716 \dots
