Solve 3.14*8^2*2+3.14*2*8*20=

$$3.14 \times 8 ^ { 2 } \times 2 + 3.14 \times 2 \times 8 \times 20 =$$

Evaluate

$$1406.72$$

Solution Steps

Calculate 8 to the power of 2 and get 64.

$$3.14\times 64\times 2+3.14\times 2\times 8\times 20$$

Multiply 3.14 and 64 to get 200.96.

$$200.96\times 2+3.14\times 2\times 8\times 20$$

Multiply 200.96 and 2 to get 401.92.

$$401.92+3.14\times 2\times 8\times 20$$

Multiply 3.14 and 2 to get 6.28.

$$401.92+6.28\times 8\times 20$$

Multiply 6.28 and 8 to get 50.24.

$$401.92+50.24\times 20$$

Multiply 50.24 and 20 to get 1004.8.

$$401.92+1004.8$$

Add 401.92 and 1004.8 to get 1406.72.

$$1406.72$$

Factor

$$\frac{7 \cdot 157 \cdot 2 ^ {5}}{5 ^ {2}} = 1406\frac{18}{25} = 1406.72$$
