Gina is adding a lace border to a circular pillow. The raduis of the pillow is approxmately 8 inches,and she needs to decide how much lace to buy. What length should she buy?
3.14x8=your answer
Pie times the radius
Circumference = 2πr = 2 * 3.14 * 8 = ?
To determine the length of lace Gina should buy, we need to find the circumference of the circular pillow.
The circumference of a circle can be found using the formula:
Circumference = 2 * π * radius
In this case, the radius of the pillow is approximately 8 inches. So we can plug this value into the formula and calculate the circumference.
Circumference = 2 * π * 8 inches
The value of π (pi) is approximately 3.14. Let's substitute this value and calculate the circumference.
Circumference = 2 * 3.14 * 8 inches
Circumference = 6.28 * 8 inches
Circumference ≈ 50.24 inches
Therefore, Gina should buy approximately 50.24 inches of lace to border the circular pillow.
