化简 16pi(0.02*(0.01^2)/2-(0.01^3)/3)

解答

化简

16 π (0.02 \cdot \frac{0.0 1 ^{2}}{2} - \frac{0.0 1 ^{3}}{3})

0.00003 \dots

求解步骤

16 π (0.02 \cdot \frac{0.0 1 ^{2}}{2} - \frac{0.0 1 ^{3}}{3})

0.02 \cdot \frac{0.0 1 ^{2}}{2} = 0.000001

\frac{0.0 1 ^{3}}{3} = 3.33333 E - 7

= 16 π (0.000001 - 3.33333 E - 7)

数字相减:

0.000001 - 3.33333 E - 7 = 6.66667 E - 7

= 16 \cdot 6.66667 E - 7 π

数字相乘:

16 \cdot 6.66667 E - 7 = 0.00001 \dots

= 0.00001 \dots π

数字相乘:

0.00001 \dots \cdot 3.14159 \dots = 0.00003 \dots

= 0.00003 \dots
