28 cm
To find the diameter of a circle when given the circumference, you can use the formula:
circumference = π * diameter
Substitute the given values:
87.92 cm = 3.14 * diameter
Solve for diameter:
diameter = 87.92 cm / 3.14
diameter ≈ 28 cm
Therefore, the diameter of the circle-shaped part of the sun is 28 cm.
