Find the area of the sheet required to make closed cylindrical vessel of height 1 m and diameter 70 cm?

Answers

Answer 1

Answer:

The area of the sheet needed is 3m^2 approx.

Step-by-step explanation:

Step one:

given

height h= 1m

diameter= 70cm= 0.7m

radius r= d/2= 0.7/2= 0.35m

The surface area or the total surface of a cylinder is equal to the sum of the base area times two and the area of the curved surface.

The formula is

T.S.A.=2πrh+2πr^2

Required is the T.S.A  

Step two:

substitute our given data we have

T.S.A.=2*3.142*0.35*1+2*3.142*0.35^2

T.S.A.=2.199+0.769

T.S.A.=2.96m^2

T.S.A.=3m^2 approx.

Find the measures of the interior angles of the triangle. A 30° B 40 С​

Answers

Answer:

A = 110°

Step-by-step explanation:

All triangles have angles that add to a sum of 180°

That means you can simply subtract angle B and C from 180 to get angle A

180 - 30 - 40 = 110°

Help this is my last question can somebody plz b help me?

Answers

Answer:

y = (4/3)x

Step-by-step explanation:

You have to find the y-intercept, b. Do this by substituting in the x and y values into the equation:

12 = (4/3)(9) + b

12 = 12 + b

b = 0

So, y = (4/3)x

Hope that helps! :D

Answer: y = 4/3x

y = -3/4x + 1 ⇔ 3x + 4y - 4 = 0

have:

(d): perpendicular to 3x + 4y - 4 = 0

     contains the point (9;12)

=> (d): 4x - 3y + 3.12 - 4.9 = 0 ⇔ 4x - 3y = 0 ⇔ y = 4/3.x

Ray and Claudia are writing in journals. Ray has written 16 pages and he now writes 2 pages every day. Claudia has written only 2 pages, but she now writes 4 pages every day. In how many days will they have written the same number of pages?

Answers

Answer:

6 days

Step-by-step explanation:

Step one:

Given data

For Ray

He has 16 pages already

Now he is writing 2 pages per day

let x be the number of days

and y be the total number of pages writen

the linear function for the situation is given as

y=2x+16-------------1

For Claudia

He has 2 pages already

Now he is writing 4 pages per day

let x be the number of days

and y be the total number of pages writen

the linear function for the situation is given as

y=4x+2-------------2

Step two:

let us equate equation 1 and 2 to find x

2x+16=4x+2

collect like terms

2x-4x=2-16

-2x=-12

divide both sides by -2

x=12/2

x=6

Therefore it will take 6 days for them to have the same number of pages

What is the solution to this equation?

O A. x= -17
B. X= -7
O c. x= 17
O D. x = 7

Answers

Answer:

x=-17

Step-by-step explanation:

Original Equation;

x+12=-5

The 12 will cross the equal sign so it will become -12. So it's going to be;

x=-5-12

There are two negative number so you add them and when you add them it would still be negative. And you would have to add them because when there are two negative numbers without any other sign you will have to add so it's going to be;

x=-17

The diagram shows ∆QRS. Which term describes point T?
A. circumcenter
B. Orthocenter
C. Incenter
D. Centroid​

Answers

Answer:

Step-by-step explanation:

A

The term which describes the point T in triangle QRS is option A. Circumcenter.

Here, given is a triangle QRS.

It is clear that three lines are drawn and all the three lines intersect at the point T.

Each of the line is perpendicular to each of the sides of the triangle.

And each of the line bisects each of the sides, that is sides are being divided in to half.

So T is the intersecting point of all the perpendicular bisectors of the sides, which is the definition of circumcenter.

Thus, T is the circumcenter of the triangle QRS.

Answers

Answer:

<R = 124°

Step-by-step explanation:

Note that the sum of angles in a triangle is 180degrees. In a triangle RST

Given

∠R=(11x+3)°

∠S=(x+15)°

∠T=(2x+8)°

Required

∠R

First we need to get the value of x;

since <R+<S+<T = 180

11x+3+x+15+2x+8 = 180

11x+x+2x+3+15+8 = 180

14x+26 = 180

14x = 180-26

14x = 154

x = 154/14

x = 11°

get <R

Since <R = 11x+3

<R = 11(11)+3

<R = 121+3

<R = 124°

Hence the measure of <R is 124°

In the diagram below, find the value of x to the nearest hundredth

Answers

Answer:

x = √324 = 18

Step-by-step explanation:

x shows up only in the second problem, so I'll focus on that problem.

This is a right triangle because one of the three angles is 90 degrees.

Thus, the Pythagorean Theorem applies:  x^2 + 24^2 = 30^2, or

x^2 = 900 - 576 = 324

Then x = √324 = 18

What is the volume of a cylinder with a diameter of 30 cm and a height of 40 cm? Use 3.14 for pie. Round to the nearest 10th.

Answers

Answer:

28,260.0 cm^3

Step-by-step explanation:

The volume of a cylinder uses the equation π[tex]r^{2}[/tex]h.To find the radius, divide the diameter by two, getting r=1/2(30)=15. Plug in all numbers getting:

3.14(15^2)(40)

=3.14(225)(40)

=28260

Answer:

V ≈ 28,260 cm³

Step-by-step explanation:

V = πr²h where,

V = volume

r = radius

h = height

π = 3.14

To find the value of the radius, we take half of the diameter.

1/2(30) = 15

Now that we have all the values, we plug them into the equation and round.

V = (3.14)(15)²(40) = 28,260

V = 28,260
