A circle is a set of points on a plane equidistant from a given point, which is the center of this circle.
The area of a circle is equal to the product of the PI number by the radius of this circle in a square:
S = π 2;
The radius of a circle is half its diameter:
r = d / 2;
r = 6/2 = 3 cm.
Now let’s find the area of this circle:
S = 3.14 * 3 ^ 2 = 3.14 9 = 28.26 cm2.
Answer: the area of the circle is 28.26 cm2.
