Answer:

area of the circle = 490.625 unit²

Explanation:

The circle is inscribed into the square ABCD . The picture illustrate a circle inscribed in a square. All the sides of a square is equal. The angles are also equal.

area of a square = L²

area of the square = 625

625 = L²

square root both sides

L = √625

L = 25

The length of each sides of the square = 25

Area of the circle = πr²

where

r = 25/2 = 12.5

area = π × 12.5²

area = 156.25π

area = 156.25 × 3.14

area of the circle = 490.625 unit²
