Answer:
never
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
Since the lines of hypotenuse are parallel,the triangles are similar
20/8 = x/18
cross multiplication
8x = 20x18
8x=360
x=45
Given:
Radius of a cylinder = 5 units.
Surface area of the cylinder = 
To find:
The height of the right cylinder.
Solution:
Surface area of a cylinder is:
Where, r is radius and h is the height of the cylinder.
Putting 
in the above formula, we get
Subtract 
from both sides.
Divide both sides by 
.
Therefore, the height of the cylinder is 11 units.
1.55 x10 to the power of 9
9
1.55x10
should look something like that
1)we calculate the volume of the right rectangular prism
volume=lenght x width x heigth
volume=12 ft * 8.5 ft * 4 ft=408 ft³
density= mass / volume ⇒ mass=volume * density.
density=0.25 pound /ft³
2) we calculate the mass of the right rectangular prism.
mass=volume * density
mass=408 ft³(0.25 pound / ft³)=102 pounds.
answer: c. 102
