Solve 2*3.14*6^2+2*3.14*6*20=

$$2 \times 3.14 \times { 6 }^{ 2 } +2 \times 3.14 \times 6 \times 20=$$

Evaluate

$$979.68$$

Solution Steps

Multiply 2 and 3.14 to get 6.28.

$$6.28\times 6^{2}+2\times 3.14\times 6\times 20$$

Calculate 6 to the power of 2 and get 36.

$$6.28\times 36+2\times 3.14\times 6\times 20$$

Multiply 6.28 and 36 to get 226.08.

$$226.08+2\times 3.14\times 6\times 20$$

Multiply 2 and 3.14 to get 6.28.

$$226.08+6.28\times 6\times 20$$

Multiply 6.28 and 6 to get 37.68.

$$226.08+37.68\times 20$$

Multiply 37.68 and 20 to get 753.6.

$$226.08+753.6$$

Add 226.08 and 753.6 to get 979.68.

$$979.68$$

Factor

$$\frac{3 \cdot 13 \cdot 157 \cdot 2 ^ {2}}{5 ^ {2}} = 979\frac{17}{25} = 979.68$$
