Solve =2*3,14*8^2+2*3,14*8*15

$$= 2 \cdot 3,14 \cdot 8 ^ { 2 } + 2 \cdot 3,14 \cdot 8 \cdot 15$$

Evaluate

$$1155.52$$

Solution Steps

Multiply 2 and 3.14 to get 6.28.

$$6.28\times 8^{2}+2\times 3.14\times 8\times 15$$

Calculate 8 to the power of 2 and get 64.

$$6.28\times 64+2\times 3.14\times 8\times 15$$

Multiply 6.28 and 64 to get 401.92.

$$401.92+2\times 3.14\times 8\times 15$$

Multiply 2 and 3.14 to get 6.28.

$$401.92+6.28\times 8\times 15$$

Multiply 6.28 and 8 to get 50.24.

$$401.92+50.24\times 15$$

Multiply 50.24 and 15 to get 753.6.

$$401.92+753.6$$

Add 401.92 and 753.6 to get 1155.52.

$$1155.52$$

Factor

$$\frac{23 \cdot 157 \cdot 2 ^ {3}}{5 ^ {2}} = 1155\frac{13}{25} = 1155.52$$
