Solve 0.18=500*x*4pi*10^-70.2/2

$$0.18= \frac{ 500 \times x \times 4 \pi \times { 10 }^{ -7 } 0.2 }{ 2 }$$

Solve for x

$$x = \frac{9000}{\pi} \approx 2864.788975654$$

Steps for Solving Linear Equation

Multiply both sides by 2.

$$0.18\times 2=500x\times 4\pi \times 10^{-7}\times 0.2$$

Multiply 0.18 and 2 to get 0.36.

$$0.36=500x\times 4\pi \times 10^{-7}\times 0.2$$

Multiply 500 and 4 to get 2000.

$$0.36=2000x\pi \times 10^{-7}\times 0.2$$

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

$$0.36=2000x\pi \times \frac{1}{10000000}\times 0.2$$

Multiply 2000 and \frac{1}{10000000} to get \frac{1}{5000}.

$$0.36=\frac{1}{5000}x\pi \times 0.2$$

Multiply \frac{1}{5000} and 0.2 to get \frac{1}{25000}.

$$0.36=\frac{1}{25000}x\pi$$

Swap sides so that all variable terms are on the left hand side.

$$\frac{1}{25000}x\pi =0.36$$

The equation is in standard form.

$$\frac{\pi }{25000}x=0.36$$

Divide both sides by \frac{1}{25000}\pi .

$$\frac{25000\times \frac{\pi }{25000}x}{\pi }=\frac{0.36\times 25000}{\pi }$$

Dividing by \frac{1}{25000}\pi undoes the multiplication by \frac{1}{25000}\pi .

$$x=\frac{0.36\times 25000}{\pi }$$

Divide 0.36 by \frac{1}{25000}\pi .

$$x=\frac{9000}{\pi }$$
