The area of the curved surface will be = 2πr × h = 2πrh
substitute
Area of the curved surface = 2πrh= 2*3.142*5*13
Area of the curved surface = 2πrh= 408.46cm^2
Hence the area of the curve surface is 408.46cm^2

Which shows a pair of similar circles ?
Answer:
d) I, II and III.
Step-by-step explanation:
Two circles are similar when the two circles have different or equal radii. In case I, we have similar circles that are congruent and non-concentric, since their radii are equal. In case II, we find two similar circles which are secant to each other. Lastly, the case III represents two similar circles which are concentric.
Therefore, I, II and III show pairs of similar circles.

Step-by-step explanation:
there are 2 multiples of 3, 3 and 6
2/8=1/4
Answer: 1/4 chance (second option on the screen)
Step-by-step explanation:
dw probability is confusing to a lot of ppl
so if you count the sections theres 8 in all
to see the probability we must find how many times we will get a positive outcome, or what we want (the multiple of 3)
lets see how many multiples of 3 there are
theres 3 and 6
thats two out of the eight possible outcomes at any moment u spin the spinner
so thats an 2/8 chance
you can simplify that fraction to a 1/4 chance, so its the second option on your screen

Mean:
Median:
Range:
Answer:
Mean: 9.2857142857143
Median: 9
Range: 11
Step-by-step explanation:
The mean is the average of the data set. Add all the numbers up then divide by the amount of numbers you had to start with.
The median of a set of data is the middlemost number. Order your set into least to greatest order then count inwards. If you have an even set or number then add both middle numbers and divide by 2.
The range of a set of data is the difference between the highest and lowest values in the set. Find your lowest and highest value numbers and subtract the lowest number form the highest one.

There are 1,000 balls in a container. All of the balls are the same size and shape. In the container, there are • 400 red balls; • 250 orange balls; • 100 green balls; and • 250 yellow balls. A student will pick one ball at random from the container. What are the probabilities that the student will pick a ball that is either red, orange, or green? Write the three different ways to represent this probability.
Answer:
I'm guessing you mean fraction decimal and percentage
The final answer is:
3/4
0.75

Step-by-step explanation:
You have to add 400 + 250 + 100 and then you will get 750. Then you make 750 into a fraction, decimal, and percentage

The probability that the student will pick a ball that is either red, orange, or green is 0.75
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the probability that the student will pick a ball that is either red, orange, or green be P
Now , the total number of balls in the container = 1000 balls
And , probability that the student will pick a ball that is either red, orange, or green can be calculated as the sum of the probabilities of picking a red ball, an orange ball, or a green ball. That is,
P(Red or Orange or Green) = P(Red) + P(Orange) + P(Green)
The probability of picking a red ball is 400/1000 = 0.4
The probability of picking an orange ball is 250/1000 = 0.25
And the probability of picking a green ball is 100/1000 = 0.1.
Therefore , P (Red or Orange or Green) = 0.4 + 0.25 + 0.1 = 0.75
Hence , the probability is 0.75

Answer:
h(x) = 1/2 |x - 1| - 2h(x) = - (x + 2)² + 3Step-by-step explanation:
See attachedYou need to recognize the parent function by looking at the graph. Then you need to find out how different is the graph from the parent function and finally work out the equation of the graph considering the transformations.
4)
The parent function is the absolute value function:
h(x) = |x|Its vertex is at the origin. We see the vertex has shifted and also the slope has changed.
We can find the slope easily, the ratio of rise to run is 1/2
The function becomes:
h(x) = 1/2 |x|Now considering the translation. We see the vertex has coordinate of (1, -2)
It means the graph has shifted 1 unit right and 2 units down.
The shift right is shown as:
h(x) = 1/2 |x - 1|and adding the shift down:
h(x) = 1/2|x - 1| - 2This is our final equation.
5)
Parabola is the graph of the quadratic function.
The vertex form of the function is:
h(x) = a(x - h)² + k, where (h, k) is the vertexNow, we see it is opening down and the vertex is at (-2, 3):
h(x) = a(x - (-2))² + 3 = a(x + 2)² + 3To find the value of a we can use a point on the graph. Let's use point (0, -1):
-1 = a(0 + 2)² + 3-1 = 4a + 34a = -4a = -1The function is:
h(x) = - (x + 2)² + 3Which is better value for money: 2 pizzas for
£12 or 4 pizzas for £28?
For the first one, each pizza is $6
For the second one, each pizza is $7
The first one is the answer
Answer:
2 pizzas for £12.
Step-by-step explanation:
[tex]\frac{2}{12}: \frac{1}{y}[/tex]
y · 2 = 12 · 1
2y = 12
2y ÷ 2 = 12 ÷ 2
y = 6
£6 for 1 at the price of 2 for £12.
[tex]\frac{4}{28}: \frac{1}{y}[/tex]
y · 4 = 28 · 1
4y = 28
4y ÷ 4 = 28 ÷ 4
y = 7
£7 for 1 at the price of 4 for £28.
