5 and 4 go into 20
Then 2 and 2 go into 4

Answer:
Arc Length : 43.98
Sector Area : 175.92
Step-by-step explanation:
Formula for Arc Length : 2·π·r·Ф / 360
Formula for Sector Area : π·
·Ф / 360
- Where <em>r </em>is the radius
- Where Ф is the angle
Arc Length : 2 · π · 8 · 315 / 360 = 43.98
Sector Area : π · 
· 315 / 360 = 175.92
hope this helps !! :D
Answer:
a. No
b. Yes
c. No
Step-by-step explanation:
a. For BC and B'C to both be parallel to the y-axis when BC is parallel to the y-axis the figure must be rotated by a multiple of 180 degrees.
b. When you rotate a figure none of the angles in the figure change.
c. For D and D' to have the same coordinates the figure must be rotated by 360.
