Whether the area of the circle is proportional to the length of its radius.

The area of a circle is directly proportional to the length of the radius of the circle. This means that the larger the value of the radius length, the larger the area of the circle. This conclusion can be made based on the formula for finding the area of a circle: S = n * R ^ 2
n – the value is constant, respectively, the value of the area will directly depend on the value of R – the length of the radius of the circle. The value of the product increases if one of the factors increases, which means that the larger the radius, the larger the area of the circle.
