What is a cylinder?

A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.

Given information:

A cereal company packs its oatmeal into cylindrical containers.

The height of each container is 10 inches, and the radius of the bottom is 4 inches

The formula for the volume of a cylinder is V = πr²h, where r is the radius of the base and h is the height.

In this case, the radius is 4 inches and the height is 10 inches. Substituting these values into the formula, we get:

V = π(4²)(10)

V = 160π

Using a calculator, we can approximate π to be 3.14 and calculate the volume:

V ≈ 160(3.14)

V ≈ 502.4

Therefore, the volume of the container is approximately 502 cubic inches.

#SPJ2

Volume = Area of the base x height
To find the area of the base (the circle on the top or bottom), we use the formula
A = π r²
A= π 4² = π 16
Now multiply by 10 (the height) and we get 10 x π x 16 or 160π in³

Some teachers allow you to leave the answer in π units. Other want you to multiply it by 3.14

So the answer is 160π in ³ or 502.4 in ³

$\sin ^( 2 ){ x } +\cos ^( 2 ){ x } =1\n \n \frac { \sin ^( 2 ){ x } }{ \sin ^( 2 ){ x } } +\frac { \cos ^( 2 ){ x } }{ \sin ^( 2 ){ x } } =\frac { 1 }{ \sin ^( 2 ){ x } } \n \n 1+\cot ^( 2 ){ x } =\csc ^( 2 ){ x }$

Because of this...

$\frac { 1 }{ 1+\cot ^( 2 ){ x } } \n \n =\frac { 1 }{ \csc ^( 2 ){ x } }$

But...

$\frac { 1 }{ \csc ^( 2 ){ x } } =\sin ^( 2 ){ x }$

Therefore:

$\frac { 1 }{ 1+\cot ^( 2 ){ x } } =\sin ^( 2 ){ x }$

jordan has been offered two summer jobs. One job is at the mall and pays $7 per hour. The other job is with your neighbor, who will pay $50 per week plus $5 per hour. How many hours per week would jordan have to week for both jobs to pay the same amount?

Answers

so, let's let P be his profit (wage) and h be total hours he is deciding to work for.

P = 7h
P = 5h + 50

These are the equations we have. Imagine they are lines on graph paper, and we have to find their intersection point (a point where an xy point is on both lines). To do this, we have to find the h and P. I'll use some algebra:

P - P = 5h + 50 - 7h
0 = -2h + 50
2h = 50
h = 25

So, after 25 hours in a week, he should have gotten the same amount of money from both jobs.

Consider quadrilateral EFGH.Quadrilateral E F G H is shown. Sides F G and E H are parallel. Angles E and H are congruent. The length of E F is 4 n minus 4, the length of F G is 3 n + 3, and the length of G H is 2 n + 6.

What is the length of line segment GH?

5 units
7 units
16 units
24 units

Answers

Given:

In quadrilateral EFGH, $FG\parallel EH,\angleE\cong \angle H,EF=4n-4,FG=3n+3, GH=2n+6$

To find:

The length of segment GH.

Solution:

Draw a figure according to the given information as shown below.

In quadrilateral EFGH, $FG\parallel EH,\angleE\cong \angle H$ , it means the quadrilateral EFGH is an isosceles quadrilateral because base angles are equal.
