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

I really dont know.

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

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?

Show me how, please.

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

So, 36 + x^2 = 100
texaschic101
  • texaschic101
subtract 36 from both sides, then take the sq rt of both sides

The result will be 8.00, am i right?

  • Goose.
Yes, that is correct.

yes

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

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

area of rectangle is L x W

Area of rectangle=48

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

The area of a circle now? The formula is \[\pi r ^{2}\]
texaschic101
  • texaschic101
area of a circle is pi * r^2.......and r = 1/2(d)....and you already know that diameter(d) = x

Approx=201.06

(3.14)(4^2) = 3.14 x 16 =
Goose.
  • 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

On step D. Should i just add the area of circle and rectangle?
Goose.
  • Goose.
Yup,
texaschic101
  • texaschic101
I am getting 50.24 for area of circle
anonymous
  • anonymous
Google said, approx=50.27
texaschic101
  • texaschic101
ok...I just used 3.14 for pi....I rounded
Goose.
  • Goose.
Plugging in basic 3.14 I got.. about 50.24
anonymous
  • anonymous
Which one is correct? 50.24 or 50.27?
Goose.
  • Goose.
Google is probably calculating it from a farther out point of Pi.
texaschic101
  • texaschic101
I would go with 50.24...but thats just me
Goose.
  • Goose.
50.27 is 'More Correct'
Goose.
  • Goose.
It's 3.14159 x r^2 then rounded up.

LOL. I put alredy 50.27

We are on Step E. Finding the perimeter of the rectangle.
Goose.
  • Goose.
This is a simple one, you know there are 2 sets of congruent sides, so just add them all up.
anonymous
  • anonymous
8+8+6+6+=22

  • anonymous
I mean =28
texaschic101
  • texaschic101
P = 2L + 2W
Goose.
  • Goose.
There you go, c:
texaschic101
  • texaschic101
correct ^^....28

Yay! lol :D

How about the entire figure? How do i calculate it?
texaschic101
  • texaschic101
don't forget to put cm or in or whatever you are measuring them with
anonymous
  • anonymous
Yea
Goose.
  • Goose.
Now your Circumference, \[2\pi r \]
texaschic101
  • texaschic101
don't forget r is half of d and d = 8
anonymous
  • anonymous
~= 25.13
Goose.
  • Goose.
The entire perimeter would just be Perimeter of Rectangle + Circumference of Circle.
Goose.
  • Goose.
Again it may vary depening on how many decimal places you go into pi, so that should be good.
anonymous
  • anonymous
Okay i'm done. THANKS! But i have 2 more question. I'll put this on new question.

Thanks guys ^_^
