Given:
A circle of radius r inscribed in a square.
To find:
The expression for the area of the shaded region.
Solution:
Area of a circle is:
Where, r is the radius of the circle.
Area of a square is:
Where, a is the side of the square.
A circle of radius r inscribed in a square. So, diameter of the circle is equal to the side of the square.
So, the area of the square is:
Now, the area of the shaded region is the difference between the area of the square and the area of the circle.
Therefore, the correct option is (a).
If triangle MAS ≅ triangle TAR, the statement that could be false is letter <span>B) segment MA ≅ segment SA.
This can be false because these two congruent triangles can be 2 scalene triangles. So, segment M</span>A can never be equal to segment SA. This can be true though, if and only if these triangles are isosceles triangles where 2 sides are equal. (See attached file to fully understand).
