To solve this, we will use the formula by which the circumference L = π * D is calculated. Let’s take π = 3.14. From the formula, you need to express the diameter of the circle:
D = L: π
D = 18.84: 3.14 As a result, we get 6 cm
Now you should apply the well-known formula to determine the area of a circle:
S = π * D² / 4
S = 3.14 * 6² / 4 = 3.14 * 9 = 28.26 cm²
Answer: an area of 28.26 cm².
