A flying disc has a circumference of 81.64 centimeters. What is the area of the flying disc? (Use 3.14 for .)

To find the area of the flying disc, we first need to find the radius of the disc.

Circumference = 2πr
81.64 = 2πr
r = 81.64 / 2π
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
