Answer:
Option A
Step-by-step explanation:
Given is a picture in which a circle is drawn within a square such that the circle touches all sides of the square.
This gives that the diameter of the circle = side of the circle
side of the circle = 7 cm. (given)
Hence area of the circle =
[tex]πr^2\\=3.14{(\frac{7}{2} ) ^2\\=38.465 cm^2[/tex]
Area of square = [tex]x^{2} =40 cm^2[/tex]
Area of shaded region= Area of square-ARea of circle
=[tex]49-38.465\\=10.535\\=10.54cm^2[/tex]
Option A is right answer.
