Q. A garden is in the shape of a circle with a radius of 1010 feet. Edging is placed around the garden.\newlineHow much edging, in feet, is needed to go around the garden? Round to the nearest whole number.
  1. Identify Formula: Step 11: Identify the formula for the circumference of a circle. The formula is C=2πr C = 2\pi r , where C C is the circumference and r r is the radius.
  2. Plug in Radius: Step 22: Plug in the given radius into the formula. The radius r r is given as 1010 feet. So, C=2π×10 C = 2\pi \times 10 .
  3. Calculate Circumference: Step 33: Calculate the circumference using the approximation π≈3.14 \pi \approx 3.14 . So, C=2×3.14×10 C = 2 \times 3.14 \times 10 .
  4. Perform Multiplication: Step 44: Perform the multiplication to find the circumference. C=2×3.14×10=62.8 C = 2 \times 3.14 \times 10 = 62.8 feet.
  5. Round to Nearest: Step 55: Round the circumference to the nearest whole number. C C is approximately 63 63 feet when rounded to the nearest whole number.
