Step-by-step explanation:
The required curved surface area =30.772 cm² and the total surface area = 1261.412 cm² for the cylinder.
The volume of a cylinder of radius 14cm is 210cm².
curved and total surface area to be determined.
The cylinder is defined as a 3D solid that keeps two identical bases joined by a curved surface, at a certain distance.
Here, Volume of cylinder(V) = 210 cm²
V=πr2h
h = V/πr2
h = 210/π*14²
h = 0.34105
Area of curved surface = 2πr*h
= 2*3.14*14*0.34
= 30.772 cm²
The total surface area of the cylinder,
A = 2πrh+2πr²
A = 2*π*14*0.34+2*π·*14²
A = 1261.412 cm²
Thus, The required curved surface area =30.772 cm² and the total surface area = 1261.412 cm² for the cylinder.

Write the equation of a circle that has a center of (-2, 1)
and a radius 3.
Answer:
Step-by-step explanation:
(x + 2)^2 + (y -1 )^2 = 3^2
(x + 2)^2 + (y -1)^2 = 9
I have used Desmos to draw this for you. Notice that the center is not (2, -1) but is at -2,1 just as the question requested. The signs are always reversed when the center of a circle must be obtained by squaring the numbers in parenthesis.
Further two points are shown. The one you should pay attention to is (-2,4) which is 3 units away from the center. The other point is also 3 units away, but you have to use the distance formula which you may not be familiar with. If you measure it with a ruler, you will find it is the same distance away from the center as (-2,4) is Since they are equal, they both must represent the length of the radius.

At the candy store, Sophie filled a bag with 2 2/3 kilograms of candy. 1/4 of the weight of the candy was from chocolate covered pretzels. How much did the chocolate covered pretzels in Sophie's bag weigh?
Answer:
The chocolate covered pretzels in Sophie's bag weighed [tex]\frac{2}{3} = 0.6667[/tex] kilograms.
Step-by-step explanation:
Sophie filled a bag with 2 2/3 kilograms of candy.
This means that the total weight is of:
[tex]2\frac{2}{3} = 2 + \frac{2}{3} = \frac{6}{3} + \frac{2}{3} = \frac{8}{3}[/tex]
The total weight is of 8/3 kilograms.
1/4 of the weight of the candy was from chocolate covered pretzels. How much did the chocolate covered pretzels in Sophie's bag weigh?
1/4 of 8/3. So
[tex]\frac{1}{4} \times \frac{8}{3} = \frac{1*8}{4*3} = \frac{2}{3} = 0.6667[/tex]
The chocolate covered pretzels in Sophie's bag weighed [tex]\frac{2}{3} = 0.6667[/tex] kilograms.

Find the surface area of the right prism :
Answer:
336 in²
Step-by-step explanation:
Surface area of triangular prism = bh + (s1 + s2 + s3)H
Where,
b = 6 in
h = 8 in
s1 = 10 in
s2 = 6 in
s3 = 8 in
H = 12 in
Surface area of triangular prism = 6*8 + (10 + 6 + 8)12
= 48 + (24)12
= 336 in²

Answer:
x = 12, x = -4.
Step-by-step explanation:
x² - 8x - 48 = 0.
This factors to (x - 12)(x + 4) = 0.
Proof:
(x - 12)(x + 4) = 0
first: x * x
outer: 4 * x
inner: -12 * x
last: -48.
first: x²
outer: 4x
inner: -12x
last: -48
x² + 4x - 12x - 48
x² - 8x - 48.
To find the zeros, take the individual pairs and find the values that make the equation 0.
x - 12 = 0
Add 12 to both sides.
x = 12.
x + 4 = 0
Subtract 4 from both sides.
x = -4.
Answer:
x= 4 + 2√5, x = 4 - 2√5
Step-by-step explanation:
So this is quadratics so you can solve it by completing the square and using the quadratic formula. The quadratic formula is x = (-b±√(b²-4ac)) / (2a).
Tell whether each number is rational or irrational.
0.121121112..
Assuming that the ".." at the end of the number represents it being continuous, then it would be irrational.
0.121121112.. is an irrational number but not rational.
What is Number system?A number system is defined as a system of writing to express numbers.
0.121121112... is rational or irrational is to consider its decimal representation and whether it is a repeating or terminating decimal.
We can see that 0.121121112... is not a terminating decimal because it goes on forever.

A line passes through the point (12,–4) and is perpendicular to the line with the equation y = 6x + 3. What's the equation of the line?
I'm just gonna so you how I got it
Step-by-step explanation:
6x - 3y - 5 = 0 has slope 6/3 = 2. A perpendicular line will have slope -1/2 (since slopes of two perpendicular lines must have a product of -1), so its general form will be 3x + 6y - a = 0.
Now to find a. We know a point on the line, (4,10), and so we plug those coordinates in:
3*4 + 6*10 - a = 0
12 + 60 - a = 0
72 = a
3x + 6y - 72 = 0.
We can simplify this by dividing all numbers by 3, getting:
x + 2y - 24 = 0

Find the approximate Perimeter of a regular hexagon that has an area of 36 mi2 and an apothem of 3.2 mi.
Area = 36 mi2
Answer:
Parameter of given regular hexagon = 22.32 mi (Approx.)
Step-by-step explanation:
Given:
Area of given regular hexagon = 36 mi²
Find:
Parameter of given regular hexagon
Computation:
Area of regular hexagon = [(3√3)/2]a²
[(3√3)/2]a² = 36
a² = [36 x 2] / 3√3
a² = [12 x 2] / √3
a² = 24 / √3
a² = 8√3
a² = 8 x 1.732
a² = 13.856
Side a = 3.72 mi (Approx.)
Parameter of given regular hexagon = 6 x Side
Parameter of given regular hexagon = 6 x 3.72

Find the area of this circle. Use 3 for .
A = ar2
8 in
[?] in?
please help
Answer:
Step-by-step explanation:
The Letter pi (π) = 3.14
The radius (r) = the diameter / 2
The diameter = 8
the radius (r)= d/2 = 8/2 = 4
The Area = 3.14 * 4*4
But they tell you to use 3 and not 3.14.
So the area = 3 * 4 * 4
The area = 48
By the way, if you are interested, the Bible uses 3 for π and not 3.14

Dalgliesh the detective fancies himself a shrewd judge of human nature. In careful tests it has been discovered that he is right 80 percent of the time when he says that a randomly chosen suspect is lying. Dalgliesh says that Jones is lying. The polygraph expert, who is right 100 percent of the time, says that 40 percent of the subjects interviewed by Dalgliesh are telling the truth. What is the probability that Jones is lying?
Answer:
The probability that Jones is lying is 6/7
Step-by-step explanation:
First we will list out 2 different cases when the outcome is a lie
1.probability that Jones tells lies is = 0.6 and probability that dalgiliesh analyses it correctly is 0.8
So the probability that dagliesh correctly analyses that he is telling lies is 0.8*0.6=0.48
2.Probability that Jones tells truth is 0.4 and if dagliesh analyses it incorrectly (which has a probability of 0.2) the outcome(as analysed by dagiliesh) is a lie
So probability that dagliesh analyses Jones truth as a lie is 0.2*.0.4=0.08
Total probability of outcome being a lie is 0.48+0.08=0.56
But we need the probability of Jones actually saying a lie which is nothing but 0.48/0.56= 6/7
