Where:
d: Is the diameter of the circumference
So:

Rounding to a decimal we have:

Answer:
RATIONAL
Step-by-step explanation:
Part A: After 9 days the radius of algae was approximately 12.81 mm. The reasonable domain to point is (0,9).
Part B: The 9 on the y-intercept represents the amount of algae the experiment started with.
Part C: (12.81-10.12)/7=0.38
