i think its 530.929cm. The formula is (pie) (radius to the second power) if you need the steps just tell me i will gladly do it for you so you will understand next time. :)
The formula for the area of a circle is: [tex]\pi {r}^{2} [/tex] If you plug in 13 for the radius and 3.14 for pi, you get: [tex]3.14 \times {13}^{2} \\ 3.14 \times 169 \\ 530.66[/tex]
