The two straight edges of the shape correspond to the original circle's radius, 5.5 cm. We're told this sector has area 30.25 cm^2, which we will use to determine the measure of the central angle subtended by the arc (the remaining edge of the shape).
The complete circle has an area of 
, which corresponds to a "central angle" of 
. Then if 
is the central angle of this sector, we have
The complete circle has a circumference of 
. Then if 
is the length of the sector's arc, we get
So the sector has a total perimeter of
5.5 cm + 5.5 cm + 11 cm = 22 cm
Answer:
1/59
Step-by-step explanation:
1/2 a 6 ounce glass is 3 ounces. He drinks 3 ounces in 2/3 of an hour.
3/2 = 1.5. He drinks 1.5 ounces in one third of an hour. 1.5 * 3 = 4.5
C. 4.5 ounces in one hour
