Answer 2

\[A = \pi r^2\]

Answer 3

\(\large \bf \textit{area of a circle}=\pi r^2\qquad r=radius\)

Answer 4

?

Answer 5

You have to do these problems serena because on the test we aren't there with you, so we gave you all the information you need for the problem, your job now is just to plug in the radius.
