Question

which point on the number line shows the position of $5pi$?
(the number line has marks at 14, 15, 16, 17, 18, 19, 20, with points a near 16, b near 17, c near 18, d near 20. options: point a, point b, point c, point d)

Explanation:

Step1: Approximate the value of $\pi$

We know $\pi \approx 3.1416$

Step2: Calculate $5\pi$

$5\pi \approx 5 \times 3.1416 = 15.708$

Step3: Match to number line point

15.708 is between 15 and 16, closest to point A.

Answer:

A. point A
