Answer: 62.8cm^2

Step-by-step explanation:

The surface area of a cylinder is calculated by 2πrh+2πr2

where π is a constant, given as 3.14; h is the height, given as 3cm and r is radius, given as 2cm.

Therefore, rh = 3 x 2= 6 cm ^2 while r^2 =2 × 2= 4 cm^2.

Slot the values into the formula:

V= 2 (3.14) x 6 + 2 (3.14) x 4

V=37.68 + 25.12

V=62.8cm ^2

I hope this helps

How do I solve this graph
Sunny_sXe [5.5K]
Plug in two values for x, say, 0 and 1.  



Lets start with solving the equation when x=0.  

y=2(0)-3
y=0-3
y=-3.

So, when x=0, y=-3.  Graph (0, -3)

Next, x=1

y=2(1)-3
y=2-3
y=-1

So, when x=1, y=-1.  Graph (1,-1)

Draw a line between the two points, and that should be your answer!  Hope this helped :)

How can you find the value of n in this equation?
lesya692 [45]
The answer would be n=37 because…
40+n=77
subtract 40 on both sides, cancelling it out on the left side and 77-40=37 so:
n=37

Does anyone know what the inequality would be?
dsp73

Let x = number of batches.

So for every batch, you need 2 cups of flour, and you have 20 cups of flour. You cannot make a batch if you don't have the sufficient amount. So using our information, our inequality is 2x \leq 20 . However, this can be further simplified.

For this inequality, divide both sides by 2, and <u>your inequality is x\leq 10.</u> <u>In context, you can make up to 10 batches of cookies.</u>
