find the circumference of a frisbee that has a diameter of 4 inches?

C = d * pi = 4 pi = 4 * 3.14 = 12.56 in

To find the circumference of a frisbee with a diameter of 4 inches, you can use the formula for the circumference of a circle, which is C = π * d, where C represents the circumference and d represents the diameter.

Step 1: Plug in the value for the diameter:
d = 4 inches

Step 2: Substitute the value into the formula:
C = π * 4

Step 3: Multiply the values:
C = 4π

So, the circumference of the frisbee is 4π inches.
