The curved surface area of a right circular cylinder of height 14 cm is 88 cm².
Answers
Answer:
The diameter of the base of the cylinder is 2 cm.
Step-by-step explanation:
GIVEN :
As per given question we have provided that :
➣ Height of cylinder = 14 cm➣ Curved surface area = 88 cm²[tex]\begin{gathered}\end{gathered}[/tex]
TO FIND :
in the provided question we need to find :
➠ Radius of cylinder ➠ Diameter of cylinder[tex]\begin{gathered}\end{gathered}[/tex]
USING FORMULAS :
[tex]\star{\underline{\boxed{\sf{\purple{Csa = 2 \pi rh}}}}}[/tex]
[tex]\star{\underline{\boxed{\sf{\purple{d = 2r}}}}}[/tex]
➛ Csa = Curved surface area ➛ π = 22/7➛ r = radius ➛ h = height ➛ d = diameter[tex]\begin{gathered}\end{gathered}[/tex]
SOLUTION :
Firstly, finding the radius of cylinder by substituting the values in the formula :
[tex] \begin{gathered} \qquad{\longrightarrow{\sf{Csa = 2 \pi rh}}} \\ \\ \qquad{\longrightarrow{\sf{88 = 2 \times \dfrac{22}{7} \times r \times 14}}} \\ \\ \qquad{\longrightarrow{\sf{88 =\dfrac{44}{7} \times r \times 14}}} \\ \\ \qquad{\longrightarrow{\sf{88 =\dfrac{44}{\cancel{7}}\times r \times \cancel{ 14}}}} \\ \\ \qquad{\longrightarrow{\sf{88 =44 \times r \times 2}}} \\ \\ \qquad{\longrightarrow{\sf{88 =88 \times r}}} \\ \\ \qquad{\longrightarrow{\sf{r = \frac{88}{88}}}} \\ \\ \qquad{\longrightarrow{\underline{\underline{\sf{\pink{r = 1 \: cm}}}}}} \end{gathered}[/tex]
Hence, the radius of cylinder is 1 cm.
———————————————————————
Now, finding the diameter of cylinder by substituting the values in the formula :
[tex]\begin{gathered} \qquad{\longrightarrow{\sf{d = 2r}}} \\ \\ \qquad{\longrightarrow{\sf{d = 2 \times 1}}} \\ \\ \qquad{\longrightarrow{\underline{\underline{\sf{\red{r = 2 \: cm}}}}}}\end{gathered}[/tex]
Hence, the diameter of the base of the cylinder is 2 cm.
[tex]\rule{300}{2.5}[/tex]
CSA of a cylinder = 88 cm²
height = 14 cm
diameter = ?
CSA of a cylinder = 88 cm²
2πrh = 88 cm²
____[tex]2 \times \frac{22}{7} \times r \times 14 = 88 cm²[/tex]
[tex]2 \times \frac{22}{1} \times r \times2 \: = 88 cm²[/tex]
[tex]2 \times 22 \times r \times 2 = 88 cm²[/tex]
[tex]88r = 88 cm²[/tex]
[tex]r = \frac{88}{88} [/tex]
[tex]r = 1 [/tex]
____Diameter = radius + radius
= 1 + 1
= 2
____Therefore, The Diameter of the base of the cylinder is 2.What is: Factorise 7−x^2

Find the maximum area for a rectangle with a perimeter of 120 meters.
Answers
Answer:
900 m^2
Step-by-step explanation:
Let x = length, y = width
perimeter = 2x + 2y = 2(x + y) = 120. so
x + y = 60, or y = 60 - x
Area = xy = x(60 - x) = 60x - x^2
= -(x^2 - 60x + 30^2) + 30^2
= 900 - (x - 30)^2
Note (x - 30)^2 is never negative, at least zero.
When (x - 30) = 0, the area is the largest which is 900 m^2

Y’all I really don’t understand-

Answers
Answer:
1. f(x) - 7
2. The lines do not have same x-intercept
3. a(x) = f(x+7)
4. b(x) = f(x-3)
5. c(x) = f(x) + 5 and c(x) = f(x+5) are two functions that can represent c(x)
6. a. g(x) = f(x-8)
b. Slope of g(x) = 1
c. y-intercept = (0, -8)
7. a. p(x)=f(x+6) is vertical transformation of f(x) = x. f(x) is the parent function.
b.(please check explanation section.)
For the second page, here are the answers
5.
a. False
The slope of f(x) will be steeper than m(x)
b. False
The y-intercept doesn't change due to multiplication of 3/5
6. C. h(x) = 3f(x-5)
7. d(x) = 1/4 f(x) + 9
8. Erika: c(x) = 4f(x) + 4 is the first graph
Landry: c(x) = -4f(x) + 3 is the second graph
Step-by-step explanation:
1. f(x) - 7 = x - 7 ( y intercept is translated down when g(x) = x - k )
2. The lines do not have same x-intercept. ( x-intercept of f(x)=x is (0,0) and that of f(x-10) is (0,10)
3. a(x) = f(x) + 7 = x + 7 = f(x+7)
4. b(x) = f(x) - 3 = x - 3 = f(x-3)
5. c(x) = f(x) + 5 = x + 5 = f( x+5)
c(x) = f(x) + 5 and c(x) = f(x+5) are two functions that can represent c(x)
6. a. g(x) = f(x) - 8 = x -8 = f(x-8)
b. Slope of g(x) = Slope of f(x)
Slope of f(x) = d(f(x)/dx = dx/dx = 1
Therefore Slope of g(x) = Slope of f(x) = 1
c. y-intercept = (0, -8) (In this case The y-intercept of g (x)=f(x-8) is translated down as -8<0 by 8 units.)
7. b. Look at the graph for part b
Now for the second page, here are the steps

Nick was surveying his field and saw some cows and ducks. Nick counted a total of 80 heads and
248 legs. Assuming there are no mutations in the animals, determine exactly how many ducks and
cows he saw. Let X represent the number of ducks and y represent the cows.
Total Equation:
Legs Equation:
How many ducks?
How many cows?
Answers
Answer:
44 cows and 36 ducks.
Step-by-step explanation:
x is ducks and y is cows.
Assuming both have 1 head each, we can write:
x + y = 80.
Let's assume each x(cow) has 4 legs and each y(duck) has two legs.
Then we can add the numbers of legs:
2x + 4y = 248 legs
Now rearrange x + y = 80 to:
x = 80-y
and substitute:
2x + 4y = 248 legs
2(80-y) + 4y = 248 legs
160 - 2y + 4y = 248 legs
2y = 88 legs
y = 44 [There are 44 cows]
Use this value to find the number of ducks:
x + y = 80
44 + y = 80
y = 36 [There are 36 ducks]
========================
Check:
Do 44 cows and 36 ducks have a total of 248 legs?
4*44 + 2*36 = 248 ?
176 + 72 = 248?

Levi is planning a road trip. He throws a dart on a map of the United States to decide where to go. There are 4 states that start with the letter A, 3 states that start with the letter C, and 8 states that start with the letter M. What is the probability that Levi throws a dart on a state that starts with an A or an M? (Hint: There are 50 total states.)
P(A∪M)=
1) 0.01
2) 0.24
3) 0.64
4) 0.42
Answers
Answer:
since there are 4 states that start with A and 8 that start with M, this means that out of the 50 states there are 12 states that he could throw a dart at and get either A or M, meaning that 12/50 is the fraction and 12/50 converted into a percentage or decimal is 0.24 meaning that 0.24 is the probability that he throws a dart and hits a state that starts with an A or M

Jim is 4 years older than mark if the sum of their ages is 44 find the age of each person
Answers
Answer:
jim is 24 years old, Mark is 20 years old
Step-by-step explanation:
This prompt can be set up using this equation:
Let's represent Mark's age by variable m and Jim's age by variable J.
j + m = 44
m + 4 = j
m = j - 4
j + (j - 4) = 44
2j - 4 = 44
2j = 48
j = 24
So, jim is 24 years old, meaning mark must be 20 years old. 20 + 24 results in 44 years old together.
