Given:
radius = 6ft
area of a sector = 59.66 ft²
π = 3.14
Find: central angle (missing one)
Solution:
To solve for the central angle given radius and area of a sector, we have the formula below:

Let's plug in the given data above to the formula.

Then, solve for θ.

Therefore, the measure of the central angle is 190 degrees.
To summarize:
radius = 6ft
central angle = 190 degrees
area of a sector = 59.66 ft²
