Distance Formula:

Given the two points (x1, y1) and (x2, y2), the distance between these points is given by the formula:

Distance Formula

Don't let the subscripts scare you. They only indicate that there is a "first" point and a "second" point; that is, that you have two points. Whichever one you call "first" or "second" is up to you.

Find the distance between the points (-2, -3) and (-4, 4).
Just plug them in to the Distance Formula:

Then the distance is sqrt(53), or about 7.28, rounded to two decimal places.

d = sqrt(53)

THIS IS WHAT MY TEACHER GAVE ME

1. If a hexagon has a side of 3 units, what is the area of the hexagon?

side= 3 units area of hexagon= (3xsqrt3 s2)/2

(3xsqrt3 32)/2

(5.2x9)/2

area= 23.4

2.If a hexagon has an area of 100 units, what is the length of one side?

area= 100 units formula= A= (3xsqrt3 s2)/2

100=(3xsqrt3 s2)/2

200=(3xsqrt3 s2)

200=(5.2x9s2)

200=23.4s2

200/23.4=s2

s2=8.55

3.If a hexagon has a radius (center to point of angle) of 6, what is the side of the hexagon?

radius=6 so each section is 60 degrees.

sin60(6)=5.2

a=bh/2 - (5.2x6)/2

area= 93.6      93.6=(3xsqrt3s2)/2

                      187.2=(3xsqrt3s2)

                      187.2/5.2=36/6=6

the side of the hexagon would be 6

5. If a hexagon is resting on a flat side, and has a total height of 18, what is the length of each side of the hexagon?

one side of a hexagon has 3 sides so if one side has a height of 18 then: 18/3 is 6. so each side would measure 6.

6.If a hexagon is resting on a flat side, and has a total height of 18, what is the area of the hexagon?

A = 9^2 x 6 * tan x (180/6)
A = 280.59



In problems 1-3, please explain the formula that you've used.

#5 is incorrect.  The height of a hexagon extends from midpoint of one side to midpoint of the opposite side.  It's different from the diameter of the hexagon, which extends from vertex to vertex.

#6  Please explain the formula that you are showing

#9 Re: Help Me ! » PLEASE HELP fast » 2015-09-15 10:58:54

I literally have no idea what I am doing and need to finish this lesson.. PLEASE HELP

#10 Re: Help Me ! » PLEASE HELP fast » 2015-09-14 09:47:26

I will submit that to her and see what she says

#11 Re: Help Me ! » PLEASE HELP fast » 2015-09-13 09:02:57

#1

3sqrt 3x^2/2 = 23.3826859

#2

a= 3 1/4 sqrt 2 a/9 = 6.2

#3

Radius is equal to side length so that means that the side length is 6.

#4

Help

#5

3 sqrt 36^2/2 = 9

#6

3 sqrt 3 9^2/2= 210.4441731

#12 Re: Help Me ! » PLEASE HELP fast » 2015-09-12 16:16:57

#3
The radius is equal to the side length so that means that the side length is 6

#5
is 9 because half is equal to the side lengths

#4
93.530


#6
210.44

No idea on #7

#13 Re: Help Me ! » PLEASE HELP fast » 2015-09-12 16:09:32

For #1 I got 23.38
for #2 I got 6.2

#14 Re: Help Me ! » PLEASE HELP fast » 2015-09-11 14:57:54

I just don't know what number 1 is.. Can someone get me started so maybe I can catch on

#15 Re: Help Me ! » PLEASE HELP fast » 2015-09-09 12:12:25

I don't know how to do it.... I am having so much trouble. Going blank

7. Problem solver (worth 4 points): Come up with a way to find the area and volume of a football. Include in your answer a way to acquire any necessary measurements without cutting or otherwise destroying the football. Also include all necessary formulas to implement your idea. (You don't need to find actual numbers, just outline the method in step by step detail--think of all the measurements you'll need to acquire and how you'll get them.)

That is all the formulas I know

#19 Re: Help Me ! » PLEASE HELP fast » 2015-09-07 03:11:20

Triangle Area Theorem
The area A of any triangle is equal to one-half the product of any base b and corresponding height h.
Formula: A = (1/2)bh

Trapezoid Area Theorem
The area A of any trapezoid is equal to one-half the product of the height h and the sum of the bases, b1 and b2.
Formula: A = (1/2)h(b1 + b2)


Area=Base * Height /2

Sphere Area Theorem
The area A of any sphere with radius r is equal to 4(PI) times the square of the radius
Area Formula: A = 4(PI)r^2

Cylinder Area Theorem
For any right circular cylinder with radius r and height h, the total area T is two times the area of the base plus the lateral area.
Formula: T = 2(PI)rh + 2(PI)r^2

Cylinder Volume Theorem
The volume V of any cylinder with radius r and height h is equal to the product of the area of a base and the height.
Formula: V = (PI)(r^2)h

L = Ph

Right Prism Volume Postulate
The volume V of any right prism is the product of B (the area of the base) and the height h of the prism.
Volume Formula: V = Bh

MY TEACHER SAID

As I advised on August 28, these problems need to be solved with tools that you have learned in this course.  Those tools include the Pythagorean Theorem, the properties of special right triangles, or basic trigonometry ratios.
