The diameter of a circular swimming pool is 8.5 m. What is the approximate circumference of the pool? Round to the nearest tenth.
Use 3.14 for π.
Question 4 options:
16.5 m
25.2 m
26.6 m
26.7 m
The circumference of a circle is calculated using the formula: circumference = π * diameter.
Substituting in the given diameter of 8.5 m and π = 3.14, the circumference is approximately:
circumference = 3.14 * 8.5
circumference ≈ 26.71 m
Rounded to the nearest tenth, the approximate circumference of the pool is 26.7 m.
Therefore, the correct answer is 26.7 m.
