A circular disc has a diameter of 24 centimeters. What is the area of the disc?
The formula for the area of a circle is A = πr^2, where r is the radius of the circle.
The diameter of the disc is 24 centimeters, so the radius is half of that, or 12 centimeters.
Using this value for r, we can calculate the area of the disc:
A = πr^2
A = π(12)^2
A = 144π
Therefore, the area of the disc is 144π square centimeters, or approximately 452.39 square centimeters if rounded to two decimal places.
