Solve 21.2*1000/3.14*8*8*10^-6

$$\frac { 21.2 \times 1000 } { 3.14 \times 8 \times 8 \times 10 ^ { - 6 } }$$

Evaluate

$$\frac{16562500000}{157}\approx 105493630.573248408$$

Solution Steps

Cancel out 8 in both numerator and denominator.

$$\frac{21.2\times 125}{3.14\times 8\times 10^{-6}}$$

Multiply 21.2 and 125 to get 2650.

$$\frac{2650}{3.14\times 8\times 10^{-6}}$$

Multiply 3.14 and 8 to get 25.12.

$$\frac{2650}{25.12\times 10^{-6}}$$

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

$$\frac{2650}{25.12\times \frac{1}{1000000}}$$

Multiply 25.12 and \frac{1}{1000000} to get \frac{157}{6250000}.

$$\frac{2650}{\frac{157}{6250000}}$$

Divide 2650 by \frac{157}{6250000} by multiplying 2650 by the reciprocal of \frac{157}{6250000}.

$$2650\times \frac{6250000}{157}$$

Multiply 2650 and \frac{6250000}{157} to get \frac{16562500000}{157}.

$$\frac{16562500000}{157}$$

Factor

$$\frac{53 \cdot 2 ^ {5} \cdot 5 ^ {10}}{157} = 105493630\frac{90}{157} = 105493630.5732484$$
