Solve 45000*4/20^2*10^-6*3.14

$$\frac { 45000 \times 4 } { 20 ^ { 2 } \times 10 ^ { - 6 } \times 3.14 }$$

Evaluate

$$\frac{22500000000}{157}\approx 143312101.910828025$$

Solution Steps

Multiply 45000 and 4 to get 180000.

$$\frac{180000}{20^{2}\times 10^{-6}\times 3.14}$$

Calculate 20 to the power of 2 and get 400.

$$\frac{180000}{400\times 10^{-6}\times 3.14}$$

Calculate 10 to the power of -6 and get \frac{1}{1000000}.

$$\frac{180000}{400\times \frac{1}{1000000}\times 3.14}$$

Multiply 400 and \frac{1}{1000000} to get \frac{1}{2500}.

$$\frac{180000}{\frac{1}{2500}\times 3.14}$$

Multiply \frac{1}{2500} and 3.14 to get \frac{157}{125000}.

$$\frac{180000}{\frac{157}{125000}}$$

Divide 180000 by \frac{157}{125000} by multiplying 180000 by the reciprocal of \frac{157}{125000}.

$$180000\times \frac{125000}{157}$$

Multiply 180000 and \frac{125000}{157} to get \frac{22500000000}{157}.

$$\frac{22500000000}{157}$$

Factor

$$\frac{2 ^ {8} \cdot 3 ^ {2} \cdot 5 ^ {10}}{157} = 143312101\frac{143}{157} = 143312101.91082802$$
