Funny! I loved the pics!

so we would solve this like:

out here we are using the formula to find the circumference , to find the radius becoz radius id double of the diameter so if we find the radius , we can multiply if with 2 to get the diameter so here we go

Circumference=2*pi*r  (now we will put 62.8 as circumference , 3.14 as pi and as we dont know radius we will assume it as r)

62.8 = 2 * 3.14 * r

62.8 = 6.28 * r

62.8 = 6.28r

r = 62.8 / 6.28  ( now deviding them both will give us our radius)

r = 10cm

So now we've got our radius as 10cm and so we will multiply it by 2 to get our diameter !

10 * 2 = 20 DIAMETER 

Now we have got our answer or diameter which is 20cm!

I hope you've understood by now but if not then pls be free to ask!

i hope this helps!

and if you want to check that the answer is correct or not then you can put radius as 10 in its place and solve to get the circumference using the same formula i told u!

 C=pi*d

62.8+pi*d

d=62.8/pi

d=1.99

$$\\cot^{-1}(-\sqrt3)=tan^{-1}\left(\frac{-1}{\sqrt3}\right)\\\\
\mbox{ The first quadrant answer is } \pi/6\quad \mbox{ But the first quadrant in not correct.}\\\\$$

this is the range of the function.

so

answer is     $$-\pi/6$$

Not two i think many more becoz on one (or two) of my posts i saw me having minus 8 points on each of my answer of that question!

But i just cant do much except for requestion people to tell me about their likes about my posts!If they tell me this can prevent me from getting more minus points!

71 with the info you provided

Its weird that you had minus two too so its not just one person behind this its two

Zegroes i too dont know what people like and what they dont and what they r doing!That is why im requestion everyone to tell me freely if they dont like any kind of thing i post of mine but not give me minus points behind my back!

People just dont like roses do they?Yeah i saw golden leaf have minus too?i dont know whats going on?i havent been on in a few days?

Sonic , i think your question is incomplete!please check your question again!

Thank you very much Melody!Your answer is also as fantastic as ours!

Whoo!THAT WAS AS EXCITING AS READING A NEWSPAPER!GOOD JOB MELODY!

Thanks. :)

NOT IN AMERICA

They are both fantastic answers.  Thank you very much.  

Actually I have  a 3rd answer.

(5a+5)(5a+5)    This is a perfect square so there is a nice short cut  

 $$\boxed{(a+b)^2=a^2+2ab+b^2}$$

so

$$(5a+5)^2\\\\
=(5a)^2+2*25a+5^2\\\\
=25a^2+50a+25$$

$$cosec^{-1}(5)= sin^{-1}(1/5)$$

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}^{\!\!\mathtt{-1}}{\left({\frac{{\mathtt{1}}}{{\mathtt{5}}}}\right)} = {\mathtt{11.536\: \!959\: \!032\: \!815^{\circ}}}$$

On the web2 calculator on the home page you have to enter asin instead of sin^-1

Inverse sine and arc sine are the same thing.  

The range of cosec^-1x is              that is in radians of course 

so    

11.53 degrees is the only answer.

oh !im sorry kitty , i just thought that it might help!

sorry!

This is enough help DragonSlayer,  you can think about some of the written answers yourself.

A line Graph would have been just as good as my column graph.  Maybe better.   

im sorry but your question does not make sense!

btw that 2 which is after 9a , is that the power of 9a, and if it is then still it can not be solved !

I am online!

Dragonslayer , if you scroll down to the bottom of this page you will be able to see all those users who are online!

so before asking check at the bottom of the page!

So we wil solve this like;

$$(5a+5)(5a+5)$$

$$=5a(5a+5)+5(5a+5)$$  (now we will multiply them)

$$=25a^2+25a+25a+25$$  (now we will add the like values)

$$=25a^2+50a+25$$   $$ANSWER$$

i hope uve understood by now but if not then pls be freee to ask!

Hope this helps!

You have to use the

First

Outside

Inside

Last

method.

5a*5a = 25a²          ---First

5a*5 = 25a        ---Outside

5*5a = 25a           ---Inside

5*5 = 25              ---Last

And now you add all these up for your answer.

25a² +25a + 25a+ 25

25a² + 50a + 25

And there you go, that's your answer.

Thanks Kitty,

Kitty has done it the usual traditional way (the way that Iwould normally do it) - I just thought I would take a look at a more basic method.

$$\\cot\;\theta=\frac{1}{tan\theta}=\frac{adj}{opp}\qquad \mbox{pos in 1st and 3rd quads}\\\\
sec\;\theta=\frac{1}{cos\theta}=\frac{hyp}{adj}\qquad \mbox{pos in 1st and 4th quads}\\\\
cosec\;\theta=\frac{1}{sin\theta}=\frac{hyp}{opp}\qquad \mbox{pos in 1st and 2nd quads}\\\\
\cot\theta\times sec\;\theta=\frac{adj}{opp}\times\frac{hyp}{adj}=\frac{hyp}{opp}=cosec\;\theta$$

Now, this obviously works in the first quadrant where everything is positive but what about in the other quadrants?

2nd quad - x - = +  true

3rd quad  + x - = -  true

4th quad - x + = -  true

In the on-site calculator just type 8255^33 and then hit enter which will then give you your answer!

Yes Melody your right , out here also we call them trapeziums !
