Find the area of the shaded part of circle Y.

201.45 cm²

Step-by-step explanation:

The whole circle has an area of π(9)² cm², or 81π cm². The shaded part represents all of the circle except for the chunk swept out by sector XZ.

Sector XZ sweeps out 75°, which represents 75/360 of the whole circle, or, simplified, 15/72. That means the shaded area must represent the other 57/72. To find the area then, we can just multiply that fraction by 81π:

Using π ≈ 3.14 and crunching the numbers out gives us a result of approximately 201.45 cm².

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes
