How many linear feet of edging are required to go around a circle with an 8 foot diameter?

• A. 24 feet
• B. 16 feet
• C. 50.24 feet
• D. 25.12 feet

Answer: (D)

Finding how far around a circle is based on the circumference formula: circumference equals π times the diameter. With a diameter of 8 feet, multiply 8 by π. Using π ≈ 3.14 gives 8 × 3.14 = 25.12 feet. This value matches the expected length around the circle and reflects a common rounding of 8π (which is about 25.1327). The other numbers don’t fit because they arise from using a different dimension (like the radius) or a different π approximation. The result around 25.12 feet is the correct edging length.
