What is the surface area of a cylinder?The surface area of a cylinder with radius r and height h is given by the following formula:
S = 2pi(r + h)
For this problem, the dimensions are given as follows:
r = 5 cm, b = 20 cm.
Hence we apply these measures to the given formula, and the surface area in square centimeters is given as follows:
S = 2pi(r + h)
S = 2pi x 5(5 + 20)
S = 250pi cm²
Hence option B is the correct surface area.

V=314
h = 25 ft
a. 1 ft
b. 2 it
C.5 ft
d. 12.3 it
I'll give Brainly
Answers
Answer:
b. 2 feet
Step-by-step explanation:
The formula for volume of a cylinder is: V=πr^2h
Start by plugging in what they give you
V=πr^2h
314 =π(r)^2(25)
314 = 25π(r)^2
divide both sides by 25π, which is 78.5
4 = r^2
take the square root of both sides
r = 2

The approximate area by Riemann Sum of the curve is represented by [tex]A = 0.4\cdot \Sigma\limits_{t = 1}^{n} [2\cdot (2+0.4\cdot t)^{3} - 4][/tex].
Step-by-step explanation:
The area below the curve is estimated by the concept of Riemann Sum with right endpoint rectangles, which is defined by the following formula:
[tex]A = \left(\frac{\Delta x}{n} \right) \cdot \Sigma \limits_{t = 1}^{n} g\left (x_{o} + \frac{\Delta x}{n}\cdot t \right)[/tex] (1)
Where:
[tex]A[/tex] - Area below the curve, in square units.
[tex]n[/tex] - Number of rectangles, no units.
[tex]x_{o}[/tex] - Lower bound of the interval, in units.
[tex]\Delta x[/tex] - Length of the interval, in units.
[tex]t[/tex] - Summation index.
If we know that [tex]g(x) = 2\cdot x^{3} - 4[/tex], [tex]n = 10[/tex], [tex]x_{o} = 2[/tex] and [tex]\Delta x = 4[/tex], then the area below the curve is represented by the following equation:

How do you write numbers more than 100?
Answers
The numerical figures are used to write numbers more than 100.
What is numbers?
An arithmetic value known as a number is used to represent a quantity and perform calculations. Numbers are represented by written symbols, such as "3," which are referred to as numerals. A number system is a method of writing that uses logically ordered digits or symbols to represent numbers.
To represent numbers greater than 100, use numeral figures; however, whole numbers, such as 300 or 1,000, should be written out.
When representing non-whole numbers like 1,239 or 603, use numerals.
Except for whole numbers combined with hundred, thousand, hundred thousand, million, billion, and beyond, the Chicago Manual of Style advises spelling out numbers from zero to one hundred and using figures after that (e.g., two hundred; twenty-eight thousand; three hundred thousand; one million).
Hence, the numerical figures are used to write numbers more than 100.

What are the coordinates of the point on the directed line segment from
3. 2) to (77) that nartitions the segment into a ratio of 3 to 2?
Answers
Answer:
(4.6, 4)
Step-by-step explanation:
Given the coordinates (3,2) and (7, 7) partitioned between 3:2
M(X,Y) = [(ax1+bx2/a+b, ay1+by2/a+b)]
X = 3(3)+2(7)/3+2
X = 9+14/5
X = 23/5
X = 4.6
Similarly;
Y = 3(2) + 2(7)/3+2
Y = 6+14/5
Y = 20/5
Y = 4
Hence the required coordinate is (4.6, 4)

y is > 7
Step-by-step explanation:
Any y value greater than 7 would make the product greater than 5. This can be looked at as y > 7. So y/7 can be rthough of as y divided by 7. 5 x y/7 can be though of as y * 5 divided by 7. Or 5y/7. To make this value 5, y must be 7. Since 7/7 is 1, and 1*5 is 5. If the number is greater than this it would have to be >7/7, since this would make it >1*5. So y must be >7. Hope this helps!

What is 85 divided by 4973?
Answers
Step Move the decimal point three places to the left in the dividend (85): 0.085
Step 2: Divide 0.085 by 4973: 0.01712
To solve 85/4973, how many times does 4973 go into 85? 0 so subtract 85 by 0, which is 0 and put a 0 with a decimal point on top of the division bar. Carry down a zero that make 85 transform to 850. How many times does 4973 go into 850? 0 so put a above the division bar and do 850 - 0 = 850. Carry a zero down making 850 into 8500. How many times does 4973 go into 8500? 1 so put it above the division bar and subtract 4973 from 8500 = 3527. Carry down a zero to make 3527 into 35270. How many times does 4973 go into 35279? 7 so write it above the division bar. Above the division bar, you should have 0.017. Round it to the nearest hundredth, which is 0.02 since 7 rounds up a number.

The sum of three consecutive integers is 27. Find the value of the greatest of the three.
Answers
Answer: The greatest of the three is 10.
Step-by-step explanation:
27/3=9 so the numbers will be around nine.
8+9+10=27
Answer:
Let x represent the value of the smallest of the three consecutive integers.
Then, the value of the middle integer is x+1, and the value of the greatest integer is x+2.
Since the sum of the three integers is 27, we have:
x + (x+1) + (x+2) = 27
Combining like terms, we have:
3x + 3 = 27
Subtracting 3 from both sides, we have:
3x = 24
Dividing both sides by 3, we have:
x = 8
Therefore, the value of the smallest integer is 8, the value of the middle integer is 8+1 = 9, and the value of the greatest integer is 8+2 = 10.
Thus, the value of the greatest integer is 10.

Since 1995 the cost of a bag of groceries has increased about 2.5% each year. The equation C = 25(1.025)x will give the value of the bag of groceries after any number of years. Predict when the bag of groceries will double in price.
Answers
Answer: 28 years
Step-by-step explanation:
Given
The equation showing the value of the bag after x years is [tex]C=25(1.025)^x[/tex]
If the price of the bag increased by 2.5%, from the equation, we can deduce that
Initial cost of the bag is 25
Double of the initial value is 50
Insert it in the equation
[tex]\Rightarrow 50=25(1.025)^x\\\Rightarrow 2=1.025^x\\\text{Taking natural log}\\\Rightarrow \ln 2=x\ln (1.025)\\\\\Rightarrow x=\dfrac{\ln 2}{\ln 1.025}\\\\\Rightarrow x=28.07\approx 28[/tex]

Given ƒ(x) = − x² – 14, find ƒ (6)
Answers
Answer:

Step-by-step explanation:
substitute x = 6 into f(x) , that is
f(6) = - 6² - 14 = - 36 - 14 = - 50
Answer:
-50
Step-by-step explanation:
f ( x ) = - x² - 14
Accordingly, to find the value of f ( 6 ) you have to replace x with ( 6 ).
f ( 6 ) = - (6)² - 14
f ( 6 ) = - 36 - 14
f ( 6 ) = -50
