B. 11.33 is closer to the area of a circle with a radius of 2.1
Answer:
D
Step-by-step explanation:
The distance depends on the time.
So now we need to find the constant of variation or the constant of proportionality.
To do so we must find y(the dependent variable) and x(the independent variable).
To find the constant(k) we must find y/x
Since y/x=k
Then 2.25/.75=k
k=3
