解答ステップ

\frac{15000}{4 π ( 7.5 \cdot 1 0 ^{- 3} ) ^{2}}

数を割る:

\frac{15000}{4} = 3750

= \frac{3750}{π ( 1 0 ^{- 3} \cdot 7.5 ) ^{2}}

(1 0^{- 3} \cdot 7.5)^{2} = 0.007 5^{2}

= \frac{3750}{0.007 5 ^{2} π}

0.007 5^{2} = 0.00005625

= \frac{3750}{0.00005625 π}

数を乗じる:

3.14159 \dots \cdot 0.00005625 = 0.00017 \dots

= \frac{3750}{0.00017 \dots}

数を割る:

\frac{3750}{0.00017 \dots} = 21220659.07891 \dots

= 21220659.07891 \dots
