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:
Whatever problem choice is equivalent to 2
Step-by-step explanation:
X=7.1cm

Answer:
9
Step-by-step explanation:
This is the answer because:
1) The mode is the element that occurs most in the data set. In this case, 9 occurs 4 times.
Therefore, the answer is 9.
