Final answer:
The option close to π/3 is 1.0 (Option B), making it the best approximation among the choices given. Other options are further away from the value of π/3.
Step-by-step explanation:
The value of π (pi) is approximately 3.14159, so π/3 is approximately 1.0472. Among the options provided, the value that is close to π/3 but not equal is 1.0 (Option B).
Options like 0.5 (Option A), 1.5 (Option C), and 2.0 (Option D) are not as close to π/3 as 1.0 is. When we perform approximate math, it's important to understand that some values, while not exact, can be very indicative of the true value.
The concept of approximation is essential, especially when we need a good estimate but an exact calculation isn't necessary or feasible.
