A circle is a part of a plane bounded by a circle.
Point O is called the center of the circle. The distance from the point of the circle to the center of the circle is called the radius.
To calculate the area of a circle, we will use the formula:
S = πr ^ 2, where:
S is the area of the circle;
r is the radius of the circle;
π – 3.14.
S = 3.14 × 122 = 3.14 × 144 = 452.16 cm2.
Answer: the area of a circle is 452.16 cm2.
