Find the area of the following circle r=9 yd

The area of the circle is given by the formula A=pi*r^2 if the radius is 9yd you can simply sub it into the formula. A=pi*9^2 which then becomes A=pi*81 you can then put this into your calculator and you get approximately A=254.469 yds if you are not allowed a calculator use pi as 3.14 A=3.14*81 which gives you 254.34yds (close enough). Hope this helps
