Solve 4*3.14*5+(4div2)*(4div2)*3.14*2

$$4 \times 3.14 \times 5+(4 \div 2) \times (4 \div 2) \times 3.14 \times 2$$

Evaluate

$$87.92$$

Solution Steps

Multiply \frac{4}{2} and \frac{4}{2} to get \left(\frac{4}{2}\right)^{2}.

$$4\times 3.14\times 5+\left(\frac{4}{2}\right)^{2}\times 3.14\times 2$$

Multiply 4 and 3.14 to get 12.56.

$$12.56\times 5+\left(\frac{4}{2}\right)^{2}\times 3.14\times 2$$

Multiply 12.56 and 5 to get 62.8.

$$62.8+\left(\frac{4}{2}\right)^{2}\times 3.14\times 2$$

Divide 4 by 2 to get 2.

$$62.8+2^{2}\times 3.14\times 2$$

Calculate 2 to the power of 2 and get 4.

$$62.8+4\times 3.14\times 2$$

Multiply 4 and 3.14 to get 12.56.

$$62.8+12.56\times 2$$

Multiply 12.56 and 2 to get 25.12.

$$62.8+25.12$$

Add 62.8 and 25.12 to get 87.92.

$$87.92$$

Factor

$$\frac{2 \cdot 7 \cdot 157}{5 ^ {2}} = 87\frac{23}{25} = 87.92$$
