Answer:

BC

Step-by-step explanation:

the height of a right-angled triangle to the Hypotenuse is the square root of the product of the lengths of the 2 segments of the Hypotenuse.

so the square of the height is then the product of the 2 line segments of the Hypotenuse.

therefore

AC² = DC × BC

Which expression represents the area of the shaded region?
irina1246 [14]

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:

A_1=\pi r^2

Where, r is the radius of the circle.

Area of a square is:

Area=a^2

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.

a=2a

So, the area of the square is:

A_2=(2r)^2

A_2=4r^2

Now, the area of the shaded region is the difference between the area of the square and the area of the circle.

A=A_2-A_1

A=4r^2-\pi r^2

A=4r^2-\pi r^2

A=r^2(4-\pi )

Therefore, the correct option is (a).
