Calculate the area of the shaded sector.
11.73
11.2
11.4
11.83

The formula for the area of a circle is

A=πr²
plug in the data we know
A=π4²
A=16π

Since we only we need to find the area of the shaded section, we need to twerk this equation a bit. (remember that the shaded section is 84/360 of the original circle.)

A=84/360*16π
A=11.728
A=11.73 units²

 A=11.73 units²

Just look outside and then you’ll see where the awnser is

Understanding what? lol
