A circular tablecloth has a radius of 2.5 feet. Kyle is sewing a piece of ribbon around the edge of the tablecloth. If Kyle has exactly enough ribbon, which measurement is closest to the length of the piece of ribbon in feet?
i dont know someone helpp
To find the length of the ribbon needed to go around the edge of the circular tablecloth, we need to calculate the circumference of the circle.
The circumference of a circle is given by the formula:
C = 2πr
Where:
C is the circumference,
π is a mathematical constant approximately equal to 3.14159, and
r is the radius of the circle.
In this case, the radius is given as 2.5 feet. Substituting the value into the formula, we have:
C = 2 * 3.14159 * 2.5
Calculating this expression, we get:
C ≈ 15.70795
Since we are looking for the measurement closest to the length of the ribbon, we can round this answer to the nearest whole number. Therefore, the length of the piece of ribbon needed is approximately 16 feet.
15.7 is your answer
Lauryn gave you an answer. Here is the method:
C = π d = π 2r = 3.14 * 5 = 15.7
