Solve 1/2*3.14*22000*10^-9

$$\frac{ 1 }{ 2 \cdot 3.14 \cdot 22000 \times { 10 }^{ -9 } }$$

Evaluate

$$\frac{12500000}{1727}\approx 7237.984944991$$

Solution Steps

Multiply 2 and 3.14 to get 6.28.

$$\frac{1}{6.28\times 22000\times 10^{-9}}$$

Multiply 6.28 and 22000 to get 138160.

$$\frac{1}{138160\times 10^{-9}}$$

Calculate 10 to the power of -9 and get \frac{1}{1000000000}.

$$\frac{1}{138160\times \frac{1}{1000000000}}$$

Multiply 138160 and \frac{1}{1000000000} to get \frac{1727}{12500000}.

$$\frac{1}{\frac{1727}{12500000}}$$

Divide 1 by \frac{1727}{12500000} by multiplying 1 by the reciprocal of \frac{1727}{12500000}.

$$1\times \frac{12500000}{1727}$$

Multiply 1 and \frac{12500000}{1727} to get \frac{12500000}{1727}.

$$\frac{12500000}{1727}$$

Factor

$$\frac{2 ^ {5} \cdot 5 ^ {8}}{11 \cdot 157} = 7237\frac{1701}{1727} = 7237.9849449913145$$
