Question

Please answer Ques 19 . I have to verify my answer.

Answer 1

Step-by-step explanation:

Case 1:

circle inside square.

The diameter of circle = side of square = 4 cm

Radius = 4/2 = 2 cm

Area of square = side^2 = 4^2 = 16 cm^2

Area of circle inside square = pi*r^2 = 3.14*2^2 = 12.56 cm^2

Area left out = 16 - 12,56 = 3.44 cm^2

Case 2:

Square inside the circle. Assuming square side = 4 cm

Diameter of circle = diagonal of square = side*root2 = 4*root2

Radius = 4*root2/2 = 2*root2 cm

Area of square = 16 cm^2

Area of circle = pi*r^2 = 3.14 * 2*root2 * 2*root2 = 25.12 cm^2

Area left out = 25.12 - 16 = 9.12 cm

[Answer will change for case 2 , if circle radius is assumed same (2 cm) rather than taking square side same]
