Answer:
226.19
Step-by-step explanation:
area of a cylinder is 2 times pi times radius time height plus 2 times pi times radius squared
radius=6/2=3
height=9
substitute in your values and get 226.19cm squared

The equation would be 90/18 which would give you the cost of 5 dollars per rose
Answer:
The equation of a parallel line would be y = 2x + 4
Step-by-step explanation:
In order to find the equation of this line, we first have to note that paralell lines have same slopes. Therefore, since the original line has a slope of 2, we know the new line will have a slope of 2. Now we can use that information along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 8 = 2(x - 2)
y - 8 = 2x - 4
y = 2x + 4
