This figure has an INSIDE and an OUTSIDE area AND a TOP and a BOTTOM    ....   First let's find the INSIDE surface area.

pi x d  = circumference = pi x 2(3)     this CIRCUMFERENCE x HEIGHT = area

so for the inside:   Area  is   pi x 2(3) x18 

Now the same thing for the OUTSIDE   pi x 2(6) x 18

Add these together    SO far   pi x 2(3) x 18    +  pi x 2(6) x 18  = 108pi + 216pi = 324pi

Now the top and bottom Area = pi r^2      Subtract the smaller from the larger

   pi (6)^2  - pi (3)^2 = pi 36 - pi 9  = pi 27  = 27pi  (there are TWO of these)  or   54pi

Now add it all together   54pi  +  324pi =  376 pi  = 376 (3.14....) = 1181.24 sq mm (rounded)

Enter your equation, and hit enter

That's it

Where the anwser is, there should be a radical form. If not, work it out by hand. All i can say buddy

If the lines have the same slope, they are parallel and do not interesect.

WHere THREE lines intersect will be a POINT (x,y) that satisfies all three equations of the lines, so solve the sytem of equations for x,y and you will have your intersection point.

most likely , it measures mass in grams.

No!!. It is very irrational, almost downright silly!!!

No, since it goes on forever without repeating and cannot be put into fractional form

y = 150/0.08^14

y = 3.41061×10^17

42, the anwser to everything

The three lines should have the same slope (also known as m)

Distribute the 2

2(4x+8)

8x+16

D**n, and what else did u do?

Turn it into a decimal.

To do this, you kinda have to memorize how to do it. 

Just know that 10% is the same as .10 and 1% is .01

Think of 100% is the same as 1 and go from there

We need to find the descent of feet per sec.

To find this, use the same thing as miles per hour

Distance/ time=speed

10/4=2.5 feet per second

12/6=2 feet per second

Therefore the blue parachute falls slower

We can turn 16/250 into a thousand, by increasing the both numbers. 

Multiply by 4 and you get 64/1000

First one down

Turn the second to fraction

6.5% -> .065 ->65/1000

ThirdTurn into fraction

.062 -> 62/1000

62/1000 < 64/1000 < 65/1000

So this ^^^^^^^^^ is your anwser

A milligram, gram or kilogram

so what dude i  do the same thing se

So, i get out of school at 2:15 right?

I'm still doing HW. It's 8:30

If a bacterias population starts at 800 and doubles every hour what will the population be after one day

800 X 2^24 =13,421,772,800=1.34 X 10^10 Bacteria after 1 day.

(800x2)x24=38400

Solve for X: 1/X^2 = 49 Take the reciprocal of both sides: X^2 = 1/49 Take the square root of both sides: Answer: | | X = 1/7 or X = -1/7
