we have 19-12=7 so we have that the volume of the small part is 7*5*4=140 cubic feet and there is 14.5*12*5=870 so the area is 870+140=1010 cubic feet so we have \(\boxed{1010\text{ cubic feet }}\)

Edited reason: wrong spelling :(

so we square the diagonal to get 1600 then we subtract 2(30^2-20^2) to get 600 then add 20^2 to get 1000 then we square root it to get \(\boxed{\sqrt{1000}}\)

220^o since arc(HE) and arc(GF) are both 35^o and arc(HG) is 70^o so arc EPF is (360-35-35-70)^o=220^o and we have that arc(EPF) is \(\boxed{220^\circ}.\)

We get 

(x^4+2x^3−19x^2−32x+48)/(2x3−3x2−23x+12) when we make a common denominator and we then we factor to get 

((x−1)(x+3)(x+4)(x−4))/((2x−1)(x+3)(x−4)) which simplifies to (x^2+3x−4)/(2x−1) or \(\boxed{\dfrac{x^2+3x−4}{2x−1}}\)

\(angle:~draw~the~2~endpoints~to~the ~center ~and~ find ~that~ angle \\ length:~360/[angle]*[circumfrence]\\ area:~360/[angle]*[area ~of ~circle]\)

or

angle: draw the 2 endpoints to the center and find that angle 

length: 360/[angle]*[circumfrence]

area: 360/[angle]*[area of circle]

There are 2 values,  x=226.88639405,313.11360594.

-56 since 1/7*1/-8=1/(-56) and 1/(1/(-56))=(-56)/1=-56 so our final answer is -56

we simplify it to -1*11*0=0 so our final answer is 0

we find that sin(270)=-1
