The surface area, A, of a cylinder is given by the formula A = 2 Trh + 2nr, where ris the radius and h is the height

Mathematics

lord [1]3 years ago

Answer:

Area = 87.9646  sq. units  from A = 28*π  sq. units.

However I cannot see this in your answer list, since the numbers look all jumbled.  Choice A. looks close to it, since there is a 28...

Step-by-step explanation:

We have a cylinder with height h = 5

radius = 2

We want the surface area of this cylinder.

A = (circumference)*h  + 2*(pi)*r^2

A = ( 4*π)*5   + 2*π*(2^2)

A = 20π + 8π  =  28 π   square units

A = 87.9646 sq.. units

So for the rhombus to carry onto itself, it needs to start in one position and end up in that same position. In this case, (x,y) will need to end up on (x,y) after the reflections are done. Here what the options do:

A: y-axis, x-axis, y-axis

(x,y) -> (-x,y) -> (-x,-y) -> (x,-y)

B: x-axis, y-axis, y-axis

(x,y) -> (x,-y) -> (-x,-y) -> (x,-y)

C: y=x, x-axis, y=x, y-axis

(x,y) -> (y,x) -> (y,-x) -> (-x,y) -> (x,y)

D: x-axis, y=x, x-axis, y=x

(x,y) -> (x,-y) -> (-y,x) -> (-y,-x) -> (-x,-y)

The only option that starts as (x,y) and ends as (x,y) is C: y=x, x-axis, y=x, y-axis, therefore making that the correct answer.

The graph below shows a system of equations:
Nostrana [21]
3y = -2x + 2
y = x + 4 (Substitute the y)

3(x + 4) = -2x + 2 (Distribute)
3x + 12 = -2x + 2 (Add 3 to both sides)
+3x       +3x
------------------------------------------
12 = 1x + 2 (Subtract 2 from both sides)
-2         - 2
------------------------
10 = 1x (Divide by 1 on both sides)
10/1 = 1x/1
x = 10
