The diameter of the circle is 6 cm, then the area of this circle is?

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.
