Surface Area of a cylinder 2(π•r²)+(2π•r)•h
So
If the diameter is 8 then the radius is 4. the height is 5.
so you have, 2(3.14•4²)+(2•3.14•4)•5
solve. PEMDAS
Parentheses & Exponents first.
2(3.14•16)+(2•3.14•4)•5
2(50.24)+(6.28•4)•5
2(50.24)+(25.12)•5

Answer:
The measure of angle IJU is 20 degrees.
Step-by-step explanation:
In order to find that, we need to add the two angles together and set equal to 180 degrees. Then we can solve for x.
(3x - 7) + (17x + 7) = 180 ----> Combine like terms
20x = 180 -----> Divide by 20
x = 9
Now that we have this, we can stick the value into the equation and solve for IJU.
IJU = 3x - 7
IJU = 3(9) - 7
IJU = 27 - 7
IJU = 20
Answer:

Step-by-step explanation:
We are given that


We have to find 
To find the value of
we will multiply f(x) by g(y)

Now,



Hence,

First problem:
The answer is C because theoretically it should have a 50% of landing
heads but instead it lands heads 56% of the time. Thus this is 6% higher
than 50%. It's not D because there is not specified detail of how the
person got this data so you can assume that the person did a fair
survey/data collection.
Second problem:
So in a data size of 490, 140 of them we trout. This means that 140/490 or 28.57% of the fish are trout. This means that in a sample size of 5000 fish, 5000*0.2857 or 1428.57 are trout.
Third problem:
The Science students seem to have a higher average score because the average score of Math students are:
(32+33+34+34+35+37+39+40+40)/9=36
average score of Science students are:
(41+42+43+43+46+46+47+49+49)/9=45.111
Answer:
1 and 2) After multiplying (x+y+3)(y+1) we have
Which is an equivalent expression after applying the distributive property.
As we can see we have an one of the variables squared, so we obtain an Parabolic Cillinder
