The area of the shaded region is 72π.

Step-by-step explanation:

The radius of the circle is 24.

The angle of the shaded region is 45°.

The formula to find the Area of shaded region[tex]A=\frac{N}{360}(3.14(r^{2}))[/tex].

where N is the angle of the shaded region and r is the radius of the circle.

[tex]A=\frac{45}{360}(3.14(24^{2}))[/tex].

[tex]A=\frac{1}{8}((3.14)(24)(24))[/tex].

A=3.14× 24×3.

A=72π.

So the area of the shaded region is 72π.
