The circumference is 5.4п, see Find the area of the circle that this circle limits.

To solve this problem, we introduce a conditional variable “X”, through which we denote the area of a circle bounded by a given circle. Then, first of all, determine the radius of the circle. As a result, we get a radius equal to 5.14p / 2p = 2.57 centimeters. Then, based on the data of the problem, we will compose the following equation: X = 3.14 x 2.57 x 2.57. Solving this equation, we get X equal to 20.74 square centimeters.
Answer: the area of a circle is 20.74 square centimeters.
