Answer:
254.34cm²
Step-by-step explanation:
In order to find the area of a circle, you use the formula
[tex]A=\pi[/tex]×[tex]r^{2}[/tex], which is [tex]A=\pi (9)^{2}[/tex] if put into this problem.
You look for [tex]9^{2}[/tex] which equals 81. Then you plug it in to multiply to [tex]\pi[/tex]. Which is:
[tex]A=81\pi[/tex]
[tex]A= 254.34[/tex]
