To find the area of the flying disc, we first need to find the radius of the disc.
Circumference = 2Ï€r
81.64 = 2Ï€r
r = 81.64 / 2Ï€
r ≈ 13 cm
Now that we have the radius, we can find the area of the disc:
Area = πr^2
Area = 3.14 * 13^2
Area = 3.14 * 169
Area ≈ 530.66 square centimeters
So, the correct answer is:
A. 530.66 square centimeters
