what is the circumfrence of the circle?

(image) Diameter is 28

a. 88 **
B.86
C.66
D.44

To find the circumference of a circle, you can use the formula C = πd, where C is the circumference and d is the diameter.

Given that the diameter of the circle is 28, the formula becomes C = π(28). Using the value of π as approximately 3.14, you get:

C ≈ 3.14(28)
C ≈ 87.92

The closest answer to 87.92 is 88, so the correct answer is:

a. 88
