In the figure, angle zyx is measured in degrees. the area of
the shaded sector can be determined using the formula
which best explains the formula?
mzzyx (92)
360°
the central angle measure of the sector divided by the
total angle measure of a circle multiplied by the area of the
circle will yield the area of the sector.
the central angle measure of the sector divided by the
total angle measure of a circle multiplied by the
circumference of the circle will yield the area of the sector.
the central angle measure of the sector multiplied by the
area of the circle will yield the area of the sector.
the central angle measure of the sector multiplied by the
circumference of the circle will yield the area of the sector.
