Solve left(18div2right)^2*3.14*2+left(2div2right)^2*3.14*18

$${ \left(18 \div 2 \right) }^{ 2 } \times 3.14 \times 2+ { \left(2 \div 2 \right) }^{ 2 } \times 3.14 \times 18$$

Evaluate

$$565.2$$

Solution Steps

Divide 2 by 2 to get 1.

$$\left(\frac{18}{2}\right)^{2}\times 3.14\times 2+1^{2}\times 3.14\times 18$$

Divide 18 by 2 to get 9.

$$9^{2}\times 3.14\times 2+1^{2}\times 3.14\times 18$$

Calculate 9 to the power of 2 and get 81.

$$81\times 3.14\times 2+1^{2}\times 3.14\times 18$$

Multiply 81 and 3.14 to get 254.34.

$$254.34\times 2+1^{2}\times 3.14\times 18$$

Multiply 254.34 and 2 to get 508.68.

$$508.68+1^{2}\times 3.14\times 18$$

Calculate 1 to the power of 2 and get 1.

$$508.68+1\times 3.14\times 18$$

Multiply 1 and 3.14 to get 3.14.

$$508.68+3.14\times 18$$

Multiply 3.14 and 18 to get 56.52.

$$508.68+56.52$$

Add 508.68 and 56.52 to get 565.2.

$$565.2$$

Factor

$$\frac{2 \cdot 157 \cdot 3 ^ {2}}{5} = 565\frac{1}{5} = 565.2$$
