Final answer:
To find the radius of the circular rug with a circumference of 6.28 yards, the formula r = C / (2π) is used, where π is approximated as 3.14. By substituting the given circumference into the formula, the radius is calculated to be 1 yard.
Step-by-step explanation:
The question is asking to calculate the radius of a circular rug given its circumference. The formula for the circumference of a circle is C = 2πr, where C is the circumference, π (pi) generally approximated as 3.14, and r is the radius of the circle. To find the radius, we rearrange the formula to solve for r: r = C / (2π).
In this case, the circumference is given as 6.28 yards. Using the formula:
r = 6.28 yards / (2 × 3.14)
r = 6.28 / 6.28
r = 1 yard
Therefore, the radius of the circular rug is 1 yard.
