I've been trying to figure this out for an hour and i still don't understand how it's 72. i feel really stupid because it's probably easy to do.

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.

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

.

.

A=3.14× 24×3.

A=72π.

So the area of the shaded region is 72π.
