To determine the length of rope needed to cover a circular placemat with a diameter of 15 inches, you need to calculate the circumference of the circle, which will be the length of the rope needed to wrap around it once. The formula for the circumference 𝐶 C of a circle is: 𝐶 = 𝜋 × 𝑑 C=π×d where 𝑑 d is the diameter. Given 𝑑 = 15 d=15 inches, we get: 𝐶 = 𝜋 × 15 ≈ 47.12 inches C=π×15≈47.12 inches To convert this into yards (since there are 36 inches in a yard): 47.12 inches × ( 1 yard 36 inches ) ≈ 1.31 yards 47.12 inches×( 36 inches 1 yard )≈1.31 yards Therefore, you would need approximately 1.31 yards of rope to wrap around a 15-inch diameter placemat once.
