The diameter of a circular swimming pool is 8.5 m. What is the approximate circumference of the pool? Round to the nearest tenth.

Question

Use 3.14 for π.

Question 4 options:

16.5 m

25.2 m

26.6 m

26.7 m

Answer 1

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.
