Answer:

Step-by-step explanation:

Answer:
· Area = pi*r^2. 121 = pi*r^2. Solve for r. Circumference = 2*pi*r. plug r into that equation and solve for Circumference
Use the given functions to set up and simplify f e e t . 121 π f t 2 = f e e t = f e 2 t
Step-by-step explanation:
Answer:
Upper left corner
Step-by-step explanation:
Divide the distance D over the time T. If you travel D = 325 miles for T = 5 hours, then your speed or rate R is
R = D/T = 325/5 = 65
So you're traveling at 65 miles an hour if you travel 325 miles in 5 hours, which is what the upper left corner diagram is showing.
