    Here is the sector area formula \[A = \frac{ x }{ 360 } \times \pi r^2\]

    In this case, x is the degree of the sector (121) and r is the radius (8).

    so 121 would go in place of the x?

    yes. X is the degrees or radians of the sector. In this case, this is in degrees.

    Nevermind, the formula is different for radians. This formula is for degrees.
