Given that the diameter of a circle is 10', what is the circumference?

• A. 25.12'
• B. 31.4'
• C. 35.8'
• D. 40.0'

Answer: (B)

To find the circumference of a circle, you can use the formula: Circumference = π × Diameter In this case, the diameter of the circle is 10 feet. By substituting the value into the formula, we get: Circumference = π × 10' Using the approximation of π as 3.14: Circumference = 3.14 × 10' = 31.4' This calculation clearly shows that the circumference of a circle with a diameter of 10 feet is 31.4 feet, making it the correct choice. Understanding this formula is essential in various applications within carpentry and woodworking, as precise measurements are crucial for fitting and assembly.
