Solve 0.2*0.02/4pi10^-7(450)(1000)

$$\frac{ 0.2 \cdot 0.02 }{ 4 \pi { 10 }^{ -7 } (450)(1000) }$$

Evaluate

$$\frac{1}{45\pi }\approx 0.007073553$$

Solution Steps

Multiply 0.2 and 0.02 to get 0.004.

$$\frac{0.004}{4\pi \times 10^{-7}\times 450\times 1000}$$

Calculate 10 to the power of -7 and get \frac{1}{10000000}.

$$\frac{0.004}{4\pi \times \frac{1}{10000000}\times 450\times 1000}$$

Multiply 4 and \frac{1}{10000000} to get \frac{1}{2500000}.

$$\frac{0.004}{\frac{1}{2500000}\pi \times 450\times 1000}$$

Multiply \frac{1}{2500000} and 450 to get \frac{9}{50000}.

$$\frac{0.004}{\frac{9}{50000}\pi \times 1000}$$

Multiply \frac{9}{50000} and 1000 to get \frac{9}{50}.

$$\frac{0.004}{\frac{9}{50}\pi }$$
