Answer:
6π
Step-by-step explanation:
You have to use the formula for the circumference of a circe:
Circumference = π(diameter)
However, you do not have the diameter, you have the radius.
Diameter = radius * 2
Diameter = 3 * 2
D = 6
Now you can substitute this value back into the Circumference formula:
C = πd
C = 6π
Step-by-step explanation:
1.) 8^-4
1/8^4 = 1/4096
2.) 2^-9
1/2^9 = 1/512
3.) (-7)^-3 =1/(-7)^-3
= 1/-343
Answer:
1. rate = 30, base = 40, percentage = 12
2. rate = 6, base = 24, percentage = 25
3. rate = 16, base = 64, percentage = 25
4. rate = 4, base = 50, percentage = 20
5. rate = 75, base = 80, percentage = 60
