The formula for the surface area of a cylinder is:
2<span>π</span><span>r</span><span>h </span><span>+ </span><span>2</span><span>π</span><span>r^</span><span>2
If we substitute in the measurements that we know, you get:
2</span><span>
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
(3.5) (14) + 2</span><span>
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
(3.5)^2
If we simplify this expression, we get:
98</span><span>
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
+ 24.5</span><span>
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
If you simplify once more, you get
122.5</span><span>
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
or </span><span>≈ 384.85
Therefore, the surface area is 122.5</span>
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
or about 384.85<span>

Hey there! I'm happy to help!
Let's represent the number of days with x.
WAREHOUSE A
200-15x
WAREHOUSE B
80+25x
We want to find how many days it will take for the two warehouses to have the same amount of coal. Let's put these expressions into an equation to show that they are equal and see what x is.
200-15x=80+25x
We subtract 25x from both sides.
200-40x=80
We subtract 200 from both sides.
-40x=-120
We divide both sides by -40
x=3
Therefore, warehouse A and warehouse B will have the same amount of coal after 3 days.
Have a wonderful day! :D
Answer:
Question 2 = 15 drinks
Question 3 = 7/12
Step-by-step explanation:
Question 2:
For every drink, there are three sizes
Ratio = 1:3
There are 5 flavors
Multiply each side by 5
5:15
15 drinks
Question 3:
5 red, 6 yellow, 8 blue, 3 orange, 2 purple
Possible outcomes = 5 + 6 + 8 + 3 + 2 = 24 possible outcomes
Favourable outcomes = 6 + 8 = 14 favourable outcomes
Fraction = 14/24 = 7/12

Answer:
The total is 97/100
Step-by-step explanation:
47/100+3/100=50/100 (aka 1/2)
50/100+47/100=97/100
