Solve 3.14*(4div2)^2*5*1/3*7.8

$$3.14 \times ( 4 \div 2 ) ^ { 2 } \times 5 \times \frac { 1 } { 3 } \times 7.8$$

Evaluate

$$163.28$$

Solution Steps

Divide 4 by 2 to get 2.

$$3.14\times 2^{2}\times 5\times \frac{1}{3}\times 7.8$$

Calculate 2 to the power of 2 and get 4.

$$3.14\times 4\times 5\times \frac{1}{3}\times 7.8$$

Multiply 3.14 and 4 to get 12.56.

$$12.56\times 5\times \frac{1}{3}\times 7.8$$

Multiply 12.56 and 5 to get 62.8.

$$62.8\times \frac{1}{3}\times 7.8$$

Multiply 62.8 and \frac{1}{3} to get \frac{314}{15}.

$$\frac{314}{15}\times 7.8$$

Multiply \frac{314}{15} and 7.8 to get \frac{4082}{25}.

$$\frac{4082}{25}$$

Factor

$$\frac{2 \cdot 13 \cdot 157}{5 ^ {2}} = 163\frac{7}{25} = 163.28$$
