Lets use the process of elimination..

AN=NC and DN=NB is correct , so that's not it,
AD=BC and DC=AB is correct as well,
<D=<B and <A=<C is correct I believe, 
so the answer would be
m<A=m<C=180

find the whole perimeter of the circle
formula: pi(r)^2

I can tell you that one place you need to subtract from the total perimeter is 1/4 of the whole perimeter so just divide the perimeter by 4 then subtract that from the whole perimeter

thereisnousername · Answer

you do 30^2 then divide by 4 which gives you 225

thereisnousername · Answer

Area = (pi)*radius^2 (pi times radius squared) ,
but only given the diameter we need to find the radius:
which would be 4.9/2 = 2.45
so now we plug that into our equation:
(pi)* 2.45^2 which gives us 18.85 which we divide by 2 and get 9.8

hold on I'm taking a quiz ill get back to you in  a few

thereisnousername · Answer

I believe its the third one

thereisnousername · Answer

the last one, you just do radius times height

thereisnousername · Answer

where would the x be

thereisnousername · Answer

I think

thereisnousername · Answer

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.

(x-9-4)^2+(y(-3)^2=25

the length of the hypotenuse of a 30 60 90 triangle is 9. what is the perimeter
27/2+9/3 sqr 3
9/2+27/2 sqr3
9+27 sqr3
27+9 sqr3

thereisnousername · Answer

In a 30-60-90 triangle, the ratio of the hypotenuse to the short leg is 2:1, and the ratio of the hypotenuse to the long leg is 2:sqr3 

 So, if the long hypotenuse is 9, the short leg will be 9/2 and the long leg will be 3sqr3 / 2 

 Adding all three sides together, we have 9/2+27/2sqr3
