find the volume of 4ft by 2ft by 3ft rectangular prism with a cylinder hole, radius 6 in., through the center
lianna [129]
Just subtract the volume of the cylinder from the volume of the rectangular prism.

Volume of rectangular prism = l x w x h = 4 x 2 x 3 = 24 ft^3
Volume of cylinder = pir^2h = pi*(6/12)^2*3 = 3/4 pi

Thus the volume would be

24 - 3/4 pi = 21.64 ft^3.

The volume would be 21.64 ft3

HELP WITH NUMBER 9 PLZ. HELPPPPPPPPPPPPPPP
Travka [436]
2|3x-6|+4=44
2|3x-6|=44-4=40
|3x-6|=40/2=20
1) condition, when 3x-6 >= 0 or x>=2, then:
3x-6=20 -> 3x=20+6=26 -> x=26/3 it is >=2.
2) condition, when 3x-6<0 or x<2, then:
-3x+6=20 -> -3x=20-6=14 -> x=-14/3 it is <2.
So, we have two roots: x1=26/3=8.66666.. and
x2=-14/3=-4.66666..
