Answer:
9π OR 28.26
Step-by-step explanation:
The formula for circumference is C = 2πr.
Substitute circumference = 18.84 for C.
18.84 = 2πr
Work backwards to find the radius of your circle.

r = 3
Now, use the formula for the area of a circle: A = π
.
Substitute r = 3 into the equation:
A = π
= 9π ≈ 28.26
The number pi is a constant, it's the ratio of a circles circumference to it's diameter.
