Answer:
y= $25-$10.50
Step-by-step explanation:
SA of a cylinder: 2

r² + 2

rh
r = radius of base
h = height of cylinder
Plug in 3 for r and 5 for h in the formula.
2

3² + 2

(3)(5)
Use a calculator to solve.
2

3² + 2

(3)(5) =
150.8 ft²
-1/2(x + 2) + 11/2 + x = 3
-1/2x - 1 + 11/2 + x = 3
1/2x + 9/2 = 3
1/2x = 3 - 9/2 = -3/2
x = -3/2 * 2 = -3
x = -3
