Convert 1450 feet to inches = 1740 inches
Tower = 24 inches
24/1740 = 2/145 .....This is the ratio of the model to the tower in inches.
Vcylinder=hpir^2
Vcone=(1/3)hpir^2
d/2=r
so
1.
d=8
r=8/2=4
h=3r
h=3(4)
h=12
V=12*3.14*4^2
V=602.88 in^2
2. cone that fits has same base area and therefor same radius
d=6
r=6/2=3
rcone=3
find height of can
V=hpir^2
21=h*3.14*3^2
21=h*3.14*9
0.7431=h
so
cone height=0.7431
radius=3
V=(1/3)(0.7431)(3.14)(3^2)
V=7 cubic units
3.
same base
find dimentions
s=s=s
V=s^3
27=s^2
3=s
Vsquarepyramid=(1/3)hs^2
s=legnth of base
h=height
h=side
V=(1/3)(3)(3^2)
V=9
C
1. 602.88 in^2
2. 7 cubic units
3. 9cm^3, C
Yes! your right. The answer is correct :)
Answer:
Expressions equivalent to 16x - 12 -24x + 4.
-8x - 8 , - (8x + 8) , 8 (-x -1) , -8 (x + 1)
Step-by-step explanation:
16x -12 -24x + 4
Arranging like terms, 16x - 24x - 12 + 4 = -8x - 8
Taking common minus, = - (8x + 8)
Taking common 8, = 8 (-x -1)
Taking common -8, = -8 (x +1)
