Do you have any idea how you would solve for X?

- anonymous

I really dont know.

- Goose.

Okay, well first thing we'll do is take a look at the rectangle.

- Goose.

We have a Slant height of 10, that slant height would be the hypotenuse of a right triangle. Do you know how to do a^2+b^2=c^2 for right triangles?

- anonymous

Show me how, please.

So, if you square 6, square X and add them together you'll get 10 squared.

- Goose.

So, if you square 6, square X and add them together you'll get 10 squared.

- Goose.

So, 36 + x^2 = 100

- texaschic101

subtract 36 from both sides, then take the sq rt of both sides

- anonymous

The result will be 8.00, am i right?

- Goose.

Yes, that is correct.

- texaschic101

yes

- Goose.

That is your 'x' Value, so you can plug that in wherever you see 'x'

- anonymous

- Goose.

The hard part is done, now it's just plugging your numbers in.

- texaschic101

area of rectangle is L x W

- anonymous

Area of rectangle=48

- Goose.

Okay, that's 2 steps down, let's keep going.

- Goose.

The area of a circle now? The formula is \[\pi r ^{2}\]

- texaschic101

area of a circle is pi * r^2.......and r = 1/2(d)....and you already know that diameter(d) = x

- anonymous

Approx=201.06

- anonymous

Oh wait wrong.

- anonymous

A=50.27

- anonymous

4squared

- texaschic101

(3.14)(4^2) = 3.14 x 16 =

- Goose.

You can put an estimate if that's what your teacher is requesting, I'd leave it at \[16\pi \]

- anonymous

yea, A=50.27

- anonymous

On step D. Should i just add the area of circle and rectangle?

- Goose.

Yup,

- texaschic101

I am getting 50.24 for area of circle

- anonymous

Google said, approx=50.27

- texaschic101

ok...I just used 3.14 for pi....I rounded

- Goose.

Plugging in basic 3.14 I got.. about 50.24

- anonymous

Which one is correct? 50.24 or 50.27?

- Goose.

Google is probably calculating it from a farther out point of Pi.

- texaschic101

I would go with 50.24...but thats just me

- Goose.

50.27 is 'More Correct'

- Goose.

It's 3.14159 x r^2 then rounded up.

- anonymous

LOL. I put alredy 50.27

- texaschic101

lol.....ok

- anonymous

We are on Step E. Finding the perimeter of the rectangle.

- Goose.

This is a simple one, you know there are 2 sets of congruent sides, so just add them all up.

- anonymous

8+8+6+6+=22

- anonymous

I mean =28

- texaschic101

P = 2L + 2W

- Goose.

There you go, c:

- texaschic101

correct ^^....28

- anonymous

Yay! lol :D

- anonymous

How about the entire figure? How do i calculate it?

- texaschic101

don't forget to put cm or in or whatever you are measuring them with

- anonymous

Yea

- Goose.

Now your Circumference, \[2\pi r \]

- texaschic101

don't forget r is half of d and d = 8

- anonymous

~= 25.13

- Goose.

The entire perimeter would just be Perimeter of Rectangle + Circumference of Circle.

- Goose.

Again it may vary depening on how many decimal places you go into pi, so that should be good.

- anonymous

Okay i'm done. THANKS! But i have 2 more question. I'll put this on new question.

- anonymous

Thanks guys ^_^

- texaschic101

no problem :)
