C = 2 pi r given r = 4
so
C = 2 pi (4)
C = 8 pi
answer
C. C = 8pi
Answer:
Step-by-step explanation:
To find the equation of this circle, we must know the center and the radius.
We can find the radius by dividing the value of the distance formula by 2 (since ):
We can then find the center of the circle by averaging the coordinates:
Then, we substitute these values into the equation of a circle:
Answer: 12.60 per CD
Step-by-step explanation:
Tax 0.80 * 3 = 2.40
40.20 - 2.40 = 37.80
37.8 / 3 = 12.60
Answer:
n + f = 15
Step-by-step explanation:
n + f = 15
n + (6) = 15
n = 15 - 6 (opposite side opposite sign)
n = 9
