In football, a field goal is worth 3 points, and the extra point after a touchdown is worth 1 point. During the 2006 season, John Kasay of the Carolina Panthers scored a total of 100 points for his team by making a total of 52 field goals and extra points. How many field goals did he make?

Shannon bought a satellite radio and a subscription to satellite radio. What is the total cost for his first year of service?

A cylindrical container of chocolate drink mix has a volume of about$\mathbf{162}\mathbf{\text{ â¶Ä‰}}\mathit{i}{\mathit{n}}^{\mathbf{3}}$. The radius of the container can be found by using the formula$\mathit{r}\mathbf{=}\sqrt{\frac{\mathbf{V}}{\mathbf{Ï€}\mathbf{h}}}$, where$\mathit{r}$is the radius and$\mathit{h}$is the height. If the height is$\mathbf{8}\mathbf{.}\mathbf{25}$inches, find the radius of the cylinder.
