The volume of a cylinder = pi r^2 h. approximating pi to be 3.14 will give you. 3.14 * (3ft)^2*4ft. this will give you 36 ft^2 times 3.14. this will give you 113.04ft^3
Answer:
= 10
Step-by-step explanation:
w + 9
if, w = 1
SO...
1 + 9 = 10
Answer:
F. 8
Step-by-step explanation:
The ratio of the long side to the short side is the same in similar triangles. The long side of triangle BAD is AD, which has length 20-4 = 16.
BD/DE = AD/BD
h/4 = 16/h
h^2 = 64 . . . . . . . multiply by 4h
h = 8 . . . . . . . . . . take the square root (matches selection F)

<em>Comment on this geometry</em>
BD = √(AD·DC) is called the "geometric mean" of the segments AD and DC. This geometry has some other geometric mean relationships as well:
BC = √(AC·DC)
BA = √(AC·AD)
