Question

Rashon wants to pour a circular concrete walkway around his reflection pond. If the diameter of the circular walkway is 12 ft (from outside to outside), what is the circumference of the outside edge of the concrete walkway? Give the answer to the nearest tenth of a foot. (1 point) Responses 18.8 ft 18.8 ft 37.7 ft 37.7 ft 113.1 ft 113.1 ft 452.4 ft

Answer 1

To find the circumference of a circular walkway, you can use the formula:

\[ C = \pi \times d \]

where \( C \) is the circumference and \( d \) is the diameter of the circle.

Given that the diameter of the circular walkway is 12 ft, we can substitute that value into the formula:

\[ C = \pi \times 12 \]

Using the approximate value of \( \pi \) as 3.14:

\[ C \approx 3.14 \times 12 = 37.68 \text{ ft} \]

Rounding this to the nearest tenth of a foot:

\[ C \approx 37.7 \text{ ft} \]

Thus, the circumference of the outside edge of the concrete walkway is approximately 37.7 ft.
