Using the formula C = 2πr, find the circumference of a circle with a diameter of 28 inches. Round your answer to the nearest inch.

To find the circumference of a circle, we can use the formula:

C = 2πr

where C is the circumference and r is the radius of the circle. Since the problem gives us the diameter, we can calculate the radius by dividing the diameter by 2:

r = Diameter / 2 = 28 inches / 2 = 14 inches

Now, we can plug the radius back into the circumference formula:

C = 2π(14 inches)

Calculating this gives:

C = 28π inches

Using an approximate value for π, which is about 3.14, we can calculate:

C ≈ 28 x 3.14 ≈ 87.92 inches

Rounding this to the nearest inch, we get:

C ≈ 88 inches

Therefore, the circumference of the circle is approximately 88 inches.
