Solve 5*2*3.14*10+2*3.14*5^2

$$5 \times 2 \times 3.14 \times 10+2 \times 3.14 \times { 5 }^{ 2 }$$

Evaluate

$$471$$

Solution Steps

Multiply 5 and 2 to get 10.

$$10\times 3.14\times 10+2\times 3.14\times 5^{2}$$

Multiply 10 and 3.14 to get 31.4.

$$31.4\times 10+2\times 3.14\times 5^{2}$$

Multiply 31.4 and 10 to get 314.

$$314+2\times 3.14\times 5^{2}$$

Multiply 2 and 3.14 to get 6.28.

$$314+6.28\times 5^{2}$$

Calculate 5 to the power of 2 and get 25.

$$314+6.28\times 25$$

Multiply 6.28 and 25 to get 157.

$$314+157$$

Add 314 and 157 to get 471.

$$471$$

Factor

$$3\times 157$$
