The formula for finding the surface area of a right circular cylinder is $S=2\pi r^2+2\pi rh$ , where S represents the surface area, r represents the radius, and h represents the height of the cylinder. Which equation can be used to find the height of a right circular cylinder in terms of its surface area and radius?

$h=\frac{S}{2\pi r}$

$h=\frac{S}{2\pi r}-r^2-r$

$h=\frac{S}{2\pi r}-r^2$

$h=\frac{S}{2\pi r}-r$

Neveah and Jason stopped by a restaraunt to eat. Neveah purchased 2 hot dogs and 1 drink for $3.75. Jasob purchased 3 hotdogs and 2 drinks for $6.00. Which system of equations can be used to determine the cost of 1 hot dog, x, and the cost of 1 drink, y?

$3x+2y=3.75$
$2x+y=6.00$

$2x+y=3.75$
$3x+2y=6.00$

$x+2y=3.75$
$2x+3y=6.00$

$2x+3y=3.75$
$x+2y=6.00$
