| Knowing the diameter of a circle, you can find its area by the formula:
S = n * ^ r2 = (n / 4) * D ^ 2;
where S is the area of the circle;
D is the diameter of the circle;
r is the radius of the circle;
n = 3.14.
The area of a circle with a diameter of 8 cm will be equal to:
S = (3.14 / 4) * 82 = 50.24 cm2.
