Solve 2*3.14*10.3*18.4+2*3.14*10.3^2

$$2 \times 3.14 \times 10.3 \times 18.4+2 \times 3.14 \times { 10.3 }^{ 2 }$$

Evaluate

$$1856.4308$$

Solution Steps

Multiply 2 and 3.14 to get 6.28.

$$6.28\times 10.3\times 18.4+2\times 3.14\times 10.3^{2}$$

Multiply 6.28 and 10.3 to get 64.684.

$$64.684\times 18.4+2\times 3.14\times 10.3^{2}$$

Multiply 64.684 and 18.4 to get 1190.1856.

$$1190.1856+2\times 3.14\times 10.3^{2}$$

Multiply 2 and 3.14 to get 6.28.

$$1190.1856+6.28\times 10.3^{2}$$

Calculate 10.3 to the power of 2 and get 106.09.

$$1190.1856+6.28\times 106.09$$

Multiply 6.28 and 106.09 to get 666.2452.

$$1190.1856+666.2452$$

Add 1190.1856 and 666.2452 to get 1856.4308.

$$1856.4308$$

Factor

$$\frac{7 \cdot 41 \cdot 103 \cdot 157}{2 ^ {2} \cdot 5 ^ {4}} = 1856\frac{1077}{2500} = 1856.4308$$
