You need the radius of the circle to be able to calculate the area of the circle.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2\pi{r}\ =\ 500]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ r\ =\ \frac{500}{2\pi}]


The area of the grass is the area of the circle minus the area of the grass.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ A_{grass}\ =\ \pi{r^2}\ -\ 120^2]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ A_{grass}\ =\ \pi\(\frac{500}{2\pi}\)^2\ -\ 14400]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ A_{grass}\ =\ \frac{250000}{4\pi}\ -\ 14400]


You can do the rest of the arithmetic.  Don't forget that the number of square yards is the number of square feet divided by 27.
