    Solution :-

    By observing the diagram given in the picture , we can say that half of side of square equal to the radius of circle

    ∵ By drawing a square of side = half of side the given square = radius of circle , and as we know that all sides of square are equal = radius . For diagram by this information kindly see the attachment .

    In mathematical form ,

    Side of square ÷ 2 = Radius of circle

    → Radius = 7/2

    Radius = 3.5 cm

    Now , finding area of circle .

    Area of circle = πr²

    ⇒ Area of circle = π(3.5)²

    ⇒ Area of circle = 22/7 × 3.5 × 3.5

    ⇒ Area of circle = 22/2 × 3.5

    ⇒ Area of circle = 11 × 3.5

    Area of circle = 38.5 cm²

    Answer:

    please follow me

    Step-by-step explanation:

    Side of the square = 7 cm

    Therefore ,

    Diameter of circle is equal to side of square

    So r = 7/2

    Area of circle = πr^2

    (22/7)×(7/2)×(7/2)

    11× (7/2)

    77/2

    38.5 CM square
