The formula for finding the circumference of a circle is C = π * d, where C is the circumference, π is the constant pi (approximately 3.14), and d is the diameter of the circle.
Given that the circumference is 87.92 cm, we can set up the equation as follows:
87.92 = 3.14 * d
Solving for d:
d = 87.92 / 3.14
d ≈ 28
Therefore, the diameter of the circle is approximately 28 cm. So the correct answer is:
28 cm
