Question

Find the area of the sector to the nearest tenth.

Answer 1

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

Answer 2

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

Answer 3

so 121 would go in place of the x?

Answer 4

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

Answer 5

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