Question

12. Diameter,
A = 72Pie
(Circle)

Answer 1

6.98

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 =
`√(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
