Answer:
8yd
Step-by-step explanation:
the diameter is the whole distance going from one end to another through the center of the circle, so if the whole distance is 16 then you can divide 16 by 2 because the radius is only half of the distance.
8 + 8 = 16yd.
If she got 9 messages last week and 3rimes as much this week then she got 27 messages because 9x3=27
3^4 means 3 to the 4th power.
This means that you would multiply 3 by itself 4 times
It would look like this...3*3*3*3
3^4=81
