Answer:

The area of the circular ends of the cylinder.

Step-by-step explanation:

The total surface area of a right circular cylinder is

... total area = area of circular ends + lateral surface area

The lateral surface area can be considered to be a rectangle whose length is the circumference of the cylinder and whose width is the height of the cylinder. For a cylinder of radius r and height h, this is described by the product ...

... lateral surface area = 2πrh

The area of the (congruent) circular ends is twice the area of one of the ends. That area is the area of a circle of radius r, so is described by ...

... area of one circular end = πr²

Then ...

... area of circular ends = 2πr²

and the total area of the cylinder is ...

... total area = 2πr² + 2πrh . . . . matches the formula in your problem statement

If you can get me some numbers this would be easier
however there's r= radius
h=height
I'm not fully understanding this

HELP IVE BEEN STRUGGLING FOR THE PAST 15 MIN PLEASEEEEE

Answer:

c= -1/2

Step-by-step explanation:

Let's solve your equation step-by-step.

4 /3 = −6c − 5/ 3

Step 1: Simplify both sides of the equation.

4 /3 =−6c + −5 /3

Step 2: Flip the equation.

−6c + −5 /3 = 4/3

Step 3: Add 5/3 to both sides.

−6c + −5 /3 + 5 /3 = 4/3 + 5 /3 −6c

Step 4: Divide both sides by -6.

−6c −6 = 3 − 6 c = −1 /2

What is the actual slope of this line?

-BARSIC- [3]

Answer:

-4

Step-by-step explanation:

The line has a "rise" between the two points of -4 units for a "run" of +1 unit. The slope is the ratio ...

m = rise/run = -4/1 = -4.

The slope is -4.

_____

Additional comment

A "whole number" must be non-negative. Here, the slope is negative. If you're restricted to "a fraction or a whole number", then the appropriate answer is the fraction -4/1. We suspect that "integer" is meant where "whole number" is used.
