July 23, 2021 | education

| A square is a regular quadrilateral in which all sides and angles are equal (all angles are 90 degrees).

The area of a square through the radius of a circle inscribed in it is found by the formula:

S = 4r ^ 2,

where r is the radius of a circle inscribed in a square.

1. If the radius r = 23 conventional units:

S = 4 * (23 ^ 2) = 4 * 529 = 2116 (conventional square units).

2. If the radius r = 18 conventional units:

S = 4 * (18 ^ 2) = 4 * 529 = 1296 (conventional square units).

Answer: 1. S = 2116 conventional square units; 2. S = 1296 conventional square units.
