Let us determine through what number of square centimeters the area of a circle will be expressed, if from the condition of the problem we know that its radius is 13 cm:

3.14 * 13 * 13 = 530.66.

Let us determine through what number of square centimeters the area of the figure will be expressed, what lies between them:

530.66-200.96. = 329.7.
