Question

12. Diameter, A = 72Pie (Circle)

Answer 1

Answer:

6.98

Step-by-step explanation:

I think that you are looking for the diameter and you are given the area of a circle.

a =$\pi r^{2}$  You are given pi, so $r^{2}$ = 72.

That means that r = $\sqrt{72}$ or a rounded answer of 8.49 rounded to the hundreds place.  The diameter is equal to 2 radius, so the diameter rounded is 16.98
