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

Y=x^2 translate 4 units down and 3 units left

klasskru [66]

Answer: Hello! When a graph is translated 4 units down you are moving all of the y values. This makes it the easiest translation that we do, other than no translation! All you have to do is subtract 4. Your equation is y=x2 - 4. If you wanted to move the graph up it is addition and if you want to move it down it is subtraction. When you translate right to left it is more complicated! Hope this helps. :))
