Question

The formula for area of a sector involves the relationship between the total area of a circle, the total angle measurement of a circle, and ______________________________?

Answer 1

we know that
area of a sector of a circle As is equal to

`As=( (angle theta)/(360))*pi* r^(2)`

where
angle theta is the central angle of the sector in degrees
360° is the total angle measurement of a circle
(pi*r²) is the total area of a circle

therefore

the answer is
the central angle of the sector (angle theta) in degrees
