1. The problem is to evaluate the expression $3.14 \times 10^9$. 2. This is a multiplication of a decimal number by a power of ten. 3. Recall that multiplying by $10^9$ means moving the decimal point 9 places to the right. 4. Starting with $3.14$, moving the decimal 9 places right gives: $$3.14 \times 10^9 = 3,140,000,000$$ 5. So, the value of $3.14 \times 10^9$ is 3140000000.
