Solve 3.14*3*4.5+3.14*5*1.5*2=

$$3.14 \times 3 \times 4.5+3.14 \times 5 \times 1.5 \times 2=$$

Evaluate

$$89.49$$

Solution Steps

Multiply 3.14 and 3 to get 9.42.

$$9.42\times 4.5+3.14\times 5\times 1.5\times 2$$

Multiply 9.42 and 4.5 to get 42.39.

$$42.39+3.14\times 5\times 1.5\times 2$$

Multiply 3.14 and 5 to get 15.7.

$$42.39+15.7\times 1.5\times 2$$

Multiply 15.7 and 1.5 to get 23.55.

$$42.39+23.55\times 2$$

Multiply 23.55 and 2 to get 47.1.

$$42.39+47.1$$

Add 42.39 and 47.1 to get 89.49.

$$89.49$$

Factor

$$\frac{3 \cdot 19 \cdot 157}{2 ^ {2} \cdot 5 ^ {2}} = 89\frac{49}{100} = 89.49$$
