Area of circle with 4 cm radius = 50.24 cm² (rounded).
A circle is a two-dimensional shape that is defined as the set of all points that are equidistant from a center point. The radius of a circle is the distance from the center point to any point on the circle. The diameter of a circle is twice the radius.
The area of a circle is the amount of space that it takes up. It is calculated using the formula pi times the square of the radius. Pi is a mathematical constant that is approximately equal to 3.14.
In the image, the radius of the circle is given as 4 centimeters. Therefore, the area of the circle is calculated as follows:
Area = pi * radius^2
Area = 3.14 * 4^2
Area = 3.14 * 16
Area = 50.24 square centimeters
Therefore, the area of the circle is 50.24 square centimeters, rounded to the nearest tenth.
