Answer:
Step-by-step explanation:
The angle of elevation
It is 
away from the point.
If we imagine a right triangle having an angle 
.
Hypotenuse
, Opposite=Height from sea level
Small Cylinder is 177.75 inches cubed. Large Cone is 471 inches cubed. Small Sphere is 26.16 inches cubed.
Based on the given figure above, here is how you get the area.
Firstly, you get the area of the part with the measurement of 4m and 4m. This has the same measurement of the sides so it is easier to find the area. The formula for the area of the square is s x s. So 4m x 4m is 16m^2. Next, get the area of the rectangle part. Getting the area of the rectangle is l x w. So 9m x 10m would be 90m^2. Now add both values and you get 106m^2. So the answer is option B.
A circle goes 360 degrees so we take the 18 and divide it, so-
360 divided by 18 which gives you 20
So the polygon has 20 sides
Hope this helps :)
