Option A is correct.
Answer:
7n = 12+ 3n
Step-by-step explanation:

To check your answer. 21 = 12+9. sure enough it matches our answer
Radius is half of the diameter.
So because the area of a circle is A= pi • r^2, to find the radius first, we have to change the equation to solve for r. Now it is, r= square root of A/pi. We plug in 1134.1. (Look at pic)
The diameter is 38
