Answer:

8.00 (3 s.f.)

Explanation:

The formula for the area of a circle is:

$A = \pi r^2$

Thus, the radius can be found by substituting A with 200.96:

$200.96 = \pi r^2$

$(200.96)/(\pi) = r^2$

$r = \pm \sqrt((200.96)/(\pi))$

r = 8.00(3.s.f)

We ignore the negative solution as it is impossible for the radius to be a negative value.
