Final answer:
The distance around a circular pond with a diameter of ten yards is found using the circumference formula, resulting in 31.42 yards.
Step-by-step explanation:
The question asks about the circumference of a circular pond with a diameter of ten yards. To find this, we use the formula for the circumference of a circle, which is C = π × d, where C is the circumference, π (pi) is approximately 3.14, and d is the diameter. For a circle with a diameter of 10 yards, the calculation would be C = 3.14 × 10 yards, which equals 31.42 yards. Therefore, the correct answer is (d) 31.42 yards.
