The circumference is 12.56 dm. What is the area of the circle bounded by this circle.

To solve this problem, you need to find the area of a circle with a known circumference. Let’s consider this task and analyze it.

According to the condition of the task, we are given the circumference.

Let’s write down the formula for the circumference and get;

C = P * D, where C is the length of the circle, P is the “PI” number equal to 3.14, D is the diameter of the circle.

From the formula for the circumference of the circle, we find the diameter of the circle and get;

D = C / P;

Substitute the values;

D = 12.56 / 3.14;

D = 4dm;

Let’s write down the formula for the area of a circle;

S = P / 4 * D2;

Substitute the values;

S = 3.14 / 4 * 42;

S = 12.56 dm2.
